Call of Duty: Advanced Warfare

Completing this easter egg will END THE GAME you are playing and start a special mode called 'Double Feature' in which you can get the achievement 'Double Tap' for killing Oz twice in Double Feature mode. My guide for that is below:

Solution for Double Tap In Call of Duty: Advanced Warfare

You must have the Reckoning DLC pack. Load up Exo Zombies > Descent.

The youtube video at the bottom of this guide is all you should really need,
however I have still included the steps in detail below.

This IS possible solo or in co-op.
There ARE variations between the solo and co-op method (however they are minor and are explained below).

---SOLO & CO-OP METHOD---

IMO, this easter egg is easier in co-op with 2 or 3 players rather than solo or with 4.

Remember to keep 2 or 3 zombies alive at the end of the rounds to allow you to more efficiently complete the steps without having to worry about killing.

To make step 4 easier DO NOT OPEN the door between the Great Hall & Galleria.

1. VALVES
Once spawned in run 1 or 2 rounds at spawn shooting in the legs and knifing for more points. Open the drop down to Reception then the door to Promenade and at the top of the stairs will be the first 3Dprinter spawn. Hit the box once each. Make your way to the Galleria and equip your exo suit ASAP. Next make your way to the Tidal Generator (you should be able to reach it by round 5). Once inside you need to find and shoot 3 valves to make them rotate enough until the light above them turns on (accurate weapons with a lot of ammo work best - you can see the valve turning when you are hitting it correctly). The three valves can be found:
1- Ground floor, on a wall to the left of the generator under the staircase
2- On the wall above a yellow door one flight up the spiral staircase
3- On the wall beside the top of the second flight of the spiral staircase
Once all three valves are turned and the lights are on above all of them the two yellow doors in the Tidal Generator room will open and reveal;
- A glowing blue screen console
- A blank black number flipboard
- An unpowered exo upgrade perk machine (teleport machine)
- A level 25 upgrade machine
The rest will be used later for now just walk up to the console and interact with it. The AI will talk. When she finishes talking, walk up to it and interact with it again and she will say "Access Denied". This step is now complete.

You will be teleported to the Oz challenge room at the end of round 5 - you do NOT need to do anything here this time.

2. UNDERWATER SWITCH
Make your way to the Lounge. Walk up to the 'Floodable Air-Lock' door and HOLD the interact button on it. A 'Depressurizing' progress graphic will appear - progress is saved - you can stop and come back and restart depressurizing from where you left off. When the blue bars reach all the way around the hexagon the AI will say "Airlock door override successful".
You now need to wait for a Goliath suit to drop into the map. It will either be dropped at spawn or at the top of the tidal generator near Exo Health. The Goliath will drop at around round 8 or 9 and will be marked on your HUD so keep an eye out for it.

While waiting for the Goliath to drop GET SET UP using the tips to survive in the additional info at the bottom of this guide

Once a Goliath drops get into it by walking up to it and interacting with it. Make your way to the Lounge WITHOUT GETTING HIT too much by zombies otherwise the Goliath will break before you can complete this step. Walk up to the Floodable Air-Lock door and interact with it. Go inside the air lock and wait for it to fill with water and open then follow the marked path towards the glowing red light. Walk up to the red light and interact with it and it will turn blue/green. Make you way back inside then either stay in the suit or self destruct it (I advise you self destruct it to make the next step possible/easier). This step is now complete and the NEXT ROUND will be the Drone Challenge.

3. DRONE CHALLENGE
FIVE drones will now spawn into the map in random locations ONE AT A TIME. If doing this coop I recommend you sweep the map staying VERY close to each other so that you can ALL catch up to and take down the drones. The possible locations for the drone to spawn that I've seen are:
-SPA near the 3dprinter OR in the corridor with the bar leading to the spa
-GREAT HALL in the middle of the room
-RECEPTION near the drop down chute from spawn OR mid-room
-PROMENADE near the bottom of the staircase
-ANNEX mid-room
-LOUNGE near the 3dprinter OR near Exo Soldier
-GALLERIA on the staircase leading up to the Exo Suit station
This step can be either very difficult or very easy depending on where the drones spawn AND where they fly to. When they fly out of the map from reception or concierge or the tidal generator it can be very difficult to take them down. Shotguns such as the S12, Blunderbus or CEL-3 seem to do well at taking these down at close range - the Trident is also very good however it may kill your remaining zombies and end the round. You need to take down all five drones BEFORE the round ends in order to complete the challenge, if you fail you can try again the very next round. Take down all drones and the challenge will be marked complete on your HUD. This step is now complete and the panel hiding a large capacitor in a wall in the Galleria will now fall off.

4. CAPACITOR CHARGING
If you kept the door closed between Galleria and Great Hall this step will be easier for you if not you'll need to be more careful. After completing step 3 a capacitor is now showing in the wall on the ground floor of Galleria near the broken aquarium. You need to let EMP / electric / shock zombies hit you while you stand near the capacitor to charge it. When an emp zombie hits you and charges the capacitor it will die. You will need about 10 emp zombies to hit you to charge it fully. I recommend you run a train of zombies and kill non EMP zombies then when the EMP zombies are leading the train run your train past the capacitor, let the EMP zombies hit you while you're beside it then kill the rest of the train if doing this solo. If doing this coop I recommend all players train away from the galleria while one person waits right next to the capacitor and kills all zombies except EMP zombies and lets EMP zombies hit them. When the round is over other players can bring their remaining EMP zombies to the capacitor. Dog rounds will help you charge the capacitor a lot as in the later rounds most of the dogs are EMP/electric dogs. You will know the capacitor is charged when the AI says capacitor charged and the capacitor has BRIGHT arcs of electricity flashing up and down it. This step is now complete and the NEXT ROUND will be the Grenade Challenge.

At round 13 you will be teleported for the second time for the FIRST OZ CHALLENGE.
To pass this challenge you need to shoot Oz behind each of the four command consoles when the bulletproof glass opens. When you kill one Oz, there will be an explosion, he will teleport to the next console and the old console will be on fire. You need to repeat this 4 times. The bulletproof glass will only open after a set amount of traps increasing in number and difficulty as well as zombie spawns as you go. The traps are:
- Laser grid ceiling: don't jump or your exo suit will reboot
- Electric floor: don't touch the floor or you will take damage
- Infected gas: don't go in the gassed areas or you will become infected and need to use the pad in the middle of the room to decontaminate.
- Turrets: sentry guns spawn on the ground floor in the lifts & automated turrets spawn on the high walls up by the ceiling - just destroy them with normal weapons.
In this room you have orbital drops that teleport in with ammo for one person in them (NOT a max ammo), contact grenades, a 3dprinter and a standard weapon upgrade machine at your disposal HOWEVER you do not earn points in this room from damaging and killing zombies. If you don't manage to kill Oz on one of the rounds and the glass closes again simply pass the challenges again and then the glass will reopen and your damage from before will have been saved. Once you take out all four Oz' there will be a large amount of orbital drops teleporting into the room with free points. Every time you collect one another one will spawn. Collect as many as you can before you are teleported back to the map (if you're fast enough you can get about 7k).

5. GRENADE CHALLENGE
1- Buy contact grenades off the wall in Spa
2- Infinite contact grenades
3- Enjoy
But seriously, that's all there is to it - this step is super easy and fun just buy contact grenades and kill the zombies with just the grenades. When you kill the last zombie the round will end and the challenge will be marked complete on your HUD. The jump challenge now appears at spawn.

6. JUMP CHALLENGE
Head to spawn. Look out over the water on the concierge drop-down side of the landing/spawn area - you will see glowing blue platforms. The aim is to reach the glowing blue circle hologram which will appear on one of the blue platforms. This will require you to use all your exo abilities (slide, jump, boost, slam) in order to parkour your way to the final platform. There are multiple stages, some easy some extremely difficult. Keep zombies at the end of the round to complete this challenge as you will need quite a lot of time to complete it. I've found that if you keep about 4 dogs on a dog round the round basically never ends however even 4 normal zombies will give you about 4 minutes. Progress through the jump challenges IS saved (you do not have to restart if a new round starts). If you fall off the platforms you will be bounced back onto the landing / spawn deck HOWEVER if you fall off very far from the glowing platforms YOU WILL DIE not down, DIE so beware of that. This step takes practice, but the more you do it the better you will get at it. When you complete all jump challenges the AI will speak and no more glowing platforms will appear. This step is now complete and the NEXT ROUND will be the Move Challenge.

7. MOVE CHALLENGE
After you complete step 6 BEFORE killing off zombies I recommend you collect supply drops and use them for this step. After you end the round after completing step 6 every movement you make (walking, running, sliding, jumping, boosting etc) will cost you points. As such either spend your points before starting the round OR use a camping tactic where you do not move.
A good tactic is to sit in a corner such as the corner of the spa near the 3d printer and set up turrets in this corner, use AI drones & have at least one person in a Goliath. This corner is good as although zombies come from both right and left the sight lines are long so if your shooting is on point and you have enough equipment from supply drops you wont have to move AT ALL.
An alternative to this is to train as you usually do and keep shooting zombies to make up for the points you're losing as you're moving. The downside is obviously that if you run out of ammo you will run out of points.
I have not risked running completely out of points yet and as such cannot confirm if this kills you or fails the challenge but it may do so (it probably fails the challenge and lets you retry next round). PLEASE CONFIRM if you have [?]
When you kill the last zombie the round will end and the challenge will be marked complete on your HUD. This step is now complete and the Simon Says game will now be active and ready for you to complete.

8. SIMON SAYS
One of the four consoles on the reception desk in Reception will now be glowing. Walk up to it and interact with it to begin the Simon Says challenge. All you have to do is remember the order of an 8 light sequence then interact with the consoles to light them back up in the order shown to you. I found the easiest way to do this is number the consoles 1,2,3,4 from left to right then just remember the number sequence. You will be shown one new number to the sequence each time until it shows you the entire 8 number sequence and you re enter it into the consoles correctly. If you have the memory of a potato, you may need to write the sequence down as you go. If you fail, the entire sequence will change and you will need to try again. If you did the Moon easter egg this is the same thing as Samantha Says, just not as fun. Once you get the final round of Simon Says correct entering all 8 of the sequenced console lights a melody will play and the consoles will no longer light up. This step is now complete and the NEXT ROUND will be the Friendly Fire Challenge.

At round 20 you will be teleported for the third time for the SECOND OZ CHALLENGE.
To pass this challenge all you have to do is avoid the same traps from the first Oz challenge (except no electric floor), turn on all four of the generators located in the corners of the room then wait for the mutated Oz to be running towards you and close then activate the decon pad. You will be able to damage mutated Oz ONLY while the decon pad is active (you will know you're not doing damage when a shield icon appears on screen). Then, simply repeat that multiple times until you kill him. Other zombie spawns will increase as you damage Oz. Good weapons to damage Oz efficiently are the Blunderbus, S12, CEL-3 & nano swarms placed directly on the decon pad. Oz will have a health bar at the top of your screen when you get this bar down to zero he will die and orbital care package points drops will teleport into the room like with the first oz challenge. Collect as many as you can before you are teleported back to the map.

This is where the co-op method differs from the solo method slightly

9. FRIENDLY FIRE CHALLENGE
If you're doing this co-op all you have to do is not shoot each other. Train in different rooms... don't use the Trident. Easy.
If you're doing this solo, you will have AI players spawn in and start shooting you doing damage to you similar to the damage from red sentinels defending the bombs on Carrier. Avoid these AI by running slow trains around the entire map and using teleporters if needed. The AI shooting at you will be marked on the map and as such shouldn't be too difficult to avoid. They cannot be killed.
Once you kill all zombies the round will end and the challenge will be marked complete on your HUD. This step is now complete and the number counter board in the Tidal Generator secret yellow room will now be active and ready for you to complete.

10. NUMBER COUNTER BOARD
After completing step 9 a number counter will now appear in the yellow secret room you opened in step 1 in the tidal generator building. This counter randomizes every game you play. There are 4 set digits on the first row that will not move. There are 4 set digits on the second row that move with different actions that you will need to match to the top row. The following actions change the following digits given that the first digit is on the left and the fourth digit is on the right.
-FIRST DIGIT: Stomping a zombie (counts even if it doesn't kill them)
-SECOND DIGIT: Player jumping (if coop any player can jump)
-THIRD DIGIT: Buying grenades from the wall
-FOURTH DIGIT: Killing any zombies or letting them die out with time
The stomps are the hardest number to match. I found the easiest way to go about matching these numbers up was Stomping a few zombies mid round running over to check the number then taking the teleport at the top of the tidal generator back to spawn then repeating until the first digit was either matched or close to being matched then not stomping anymore. Next kill off most of the zombies but keep about 10. Next buy contact grenades from the wall in Spa until the third digit matches (just waste your extra grenades by shooting them at the walls so you can buy more). Next if you only got the first number close now that there are only a few zombies left you should be able to separate them and get the exact number stomped matched. Next match the second digit by just jumping while looking at the counter then have everyone stop jumping completely. Next kill off the remaining zombies until the fourth digit matches. Once all four digits match the numbers will disappear and the AI will speak. This step is now complete and the NEXT ROUND will be the Rocket Challenge.

10. ROCKET CHALLENGE
THIS IS THE HARDEST STEP OF THE EASTER EGG (in my opinion).
As this is a difficult step I recommend you save your 'Sentinels' orbital drop as well as any other drops you can which will help for this step (such as AI drones or turrets). Activate these in the room you want to train in then immediately kill the remaining zombies to start the round. You will NOT be able to call in any equipment from orbital drops during the round. When the round starts you will be given a Mk25 upgraded MAHEM rocket launcher with unlimited ammo which although powerful, is extremely heavy and causes your player to move very slowly. You can also damage yourself with the rockets. These factors combined with a high round and lots of zombies makes this step, in my opinion, the most difficult out of any step in exo zombies to date so focus up, give it all you've got and keep those trains big and kill those zombies slowly to slow down spawns and keep yourself as safe as possible. This round is the main reason why you want to be completing easter egg steps as 'round-efficiently' as possible. Once you kill all the zombies the round will end and the challenge will be marked complete on your HUD. This step is now complete and the final step is now ready for activation.

11. MEMORY SIMULATION ROUNDS
As quickly as you can, (preferably be there before you even kill the last zombie in step 10 then kill it when you get there) make your way to the Tidal Generator secret yellow room from step 1. The teleport machine will have red glowing lights on it. ALL PLAYERS must then press the glowing blue console that you used to activate the easter egg in step 1 by walking up to it and interacting with it. The teleport machine will now light up blue and ALL PLAYERS must then walk up to it, huddle together, and interact with it. You will then be teleported into a memory simulation with a small floating map similar to the spawn area on Outbreak. There is a standard weapon upgrade machine here and nothing else for you to replenish your ammo. You must survive here without being killed by zombies or falling off the map for TWO ROUNDS. AI players that are spawned in will shoot zombies but do barely any damage, they will attract hordes of zombies so I found the best way to survive here was simply run around the map and kill off the hordes attracted to the AI. This step is easier than it sounds just make sure you keep upgrading your gun to maintain ammo and damage to keep up with the two waves.

Once you complete both rounds you will be teleported back to the map, 'Double Feature' mode will be activated and you will unlock your achievement, as well as permanently unlock Double Feature mode.

Well done!
You completed the hardest easter egg in Exo Zombies to date!

1 like = 1 cry for Oz

ADDITIONAL INFO

EXO ZOMBIES "DESCENT" EASTER EGG TUTORIAL - FULL "REUNION" ACHIEVEMENT (Advanced Warfare DLC 4)

Written and video descriptions for each step of the Easter Egg. I've also included a full video of what I believe is the most difficult step: the Jumping Puzzle.

Step 1: Valves and Secret Room


Shoot the 3 small red valves located in Tidal Generator. A blue light will appear above the valve when it is complete. Once all three are completed a hidden room will open in on the second level of this room. Enter and Hold X on the blue moniter. After the AI is done talking hold X again to complete this step.

Step 2: Pressurized Door/Goliath


Go to the Lounge and Hold X on the yellow door labeled "Floodable Air Lock". While doing so, any zombies still alive will ignore other teammates and come after you. Once the room is depressurized, you will need the Goliath support drop which will spawn on round 8 or 9. Now take the Goliath and enter the same door you just depressurized. Follow the path and melee the zombie in your way. Hold X to press the button at the end, turn around and leave.

Step 3: Drone Challenge


Five drones will spawn in random locations around the map. You must destroy them before they disappear and before the round ends or else you will have to start over on the next round. The drones can spawn in every area except the main spawn point, the roof where exo-health is located, and the tunnel leading up to exo-health. But be aware, drones can spawn near the beginning of the tunnel towards exo-health (which is also near the Exo-Suits). The main area you need to be careful with is when the drones heads towards the main spawn. They will fly right up the elevators and into the air to disappear. It is possible that one of the drones will have an upgrade inside, kill these as well.

I wouldn't suggest attempting this with one crawler left due to the time it takes to find and destroy all five drones. It is also recommened to have good (or upgraded) weapons to destroy them as fast as possible. The Blunderbust and Lynx sniper both do a lot of damage.

I also suggest that if you are playing in co-op to move as a group. The drones start to move if you get too close and if one person can't destroy it on their own then you will have to start over.

Step 4: Capacitor


After completing step 3, a panel will open up on the wall near the HBra3/Weapon Upgrade machine revealing a Capacitor. From the Exo-Suits, the panel is located on the wall to the right of the Spa entrance. For this step, you must allow Shock Zombies (or dogs) to hit you in front of the Capacitor to charge it up. Keep doing this until the Capacitor is fully charged. To see your progress, there is a display revealing "0, 25, 50, 75, 100" and an arrow to the right of them that moves up. Once you hit 100, the AI will speak and you're done.

Step 5: Grenade Challenge


One of the easiest challenges. When a new round starts, you will begin with infinite contact grenade. It doesn't matter if you didn't buy them previously or not. Simply spam grenades to kill every zombie and end the wave as fast as possible. You won't be allowed to use weapons, secondary grenades (teleport, etc.), or buy ammo or upgrades. Just spam grenades until the round is over to complete this step.

Step 6: Jumping Puzzle


This will likely be the hardest step for most people. For this step, you will need to complete a series of jumping puzzles. To begin, head to the initially spawn points and you will see two large blue squares above the water. Once you complete one puzzle, the next will spawn. You also don't have to worry about falling in the water near this area.

The hardest puzzles will likely be the two long jumps (3 and 7). It's difficult to explain in text, but you want to perform a slide, then boost forward, then double jump and slide. Now don't take that word for word. It's easier to do than explain (and it isn't easy to do!). You really have to watch the video to see what I'm talking about. It's basically a slide, then boosting forward out of it, then jump boosting, then pushing forward again.

There are nine puzzles total, after completing the last one it's on to step 7.

Step 7: Movement Challenge


At the beggining of the new round you will have the Movement Challenge. During this challenge you will lose points when you move. If you're have an excess amount of money before starting this round it would be wise to spend SOME of it. The reason you don't want to spend it all is because if you reach zero points you won't be able to move. As long as you have a decent weapon to kill zombies this challenge isn't too bad. You will still gain points from damage and kills to counteract the negative points for moving. Utilize any power-ups such as the Biohazard Bomb and Explosive Touch to end the round as fast as possible and save you points from moving. After you complete the wave be sure to not move until the challenge says "Completed" as you will still lose points until then.

Step 8: Simon Says Monitors


For this step you will need to complete a "Simon Says" style game on four computer monitors. The monitors are located near the left elevator heading up to the initial spawn point. They are to the left of this elevator. This is also the area where the 3D Printer first spawns. Hold X on the monitor with the blue glowing light to begin. After that, you will have to follow the order of lights to complete this step. If you get one wrong, you will have to start over. I suggest writing down the order to make this step much easier. For example if the far left monitor is first write down "1". Then if it is far left, far right, write down "1,4". Then far left, far right, far left, write down "1,4,1" etc.

Step 9: Friendly Fire Challenge


At the beginning of a new round you will have the Friendly Fire challenge. For this challenge Friendly Fire will be turned on and you simply have to survive the round. If you are playing in co-op, you will fail if one person kills the other. Shooting each other, however, will not fail the challenge. If you are playing Solo, three AI will spawn and will attempt to kill you. Simply finish the round to complete this challenge.

Step 10: Number Counter


In the area where you completed the first step, and the hidden room opened up, a board will appear with two sets of numbers. The top four numbers are your goal, and the bottom four are you current counter. In order to complete this step you have to have your bottom numbers match each of the top numbers. The numbers count up from 0-9 by performing the following actions:

First Number - Using Exo-Slam to hit/kill zombies
Second Number - Jump with any player
Third Number - Buying grenades off the wall
Fourth Number - Kill or letting a zombie bleed out

The Exo-Slam is located near the Exo-Suits on the way towards Exo-Health. Contact grenades can be initially purchased for 750 in the Spa and 500 for everyone afterwards. If you're counter is at 3 and the target is at 2, you will have to go up to 9 and continue to 0, 1, and then 2 to reach it. This can be done over multiple rounds and I would suggest doing the Exo-Slam and Grenade numbers first.

Step 11: Rocket Challenge


At the beginning of a new roun you will have the Rocket Challenge. You will start with a Rocket Launcher with infinite ammo and will not be able to use anything else. You can kill yourself with the Rocket Launcher so be sure to not shoot too close to yourself. There isn't any friendly fire in co-op so you can shoot zombies off your teammates to help them. We stayed in the Spa with three people continuously jumping and shooting. Complete the round to finish this challenge.

Step 12: Memory Simulation


For the last step, all players must hold X on the very first blue monitor from Step 1. After doing so, the teleporter to the right of it will be activated and you must then hold X to use it. You will be teleported to a new area in which you have to survive by any means to complete the Easter egg. Use any weapons, orbital drops, and anything else you have to survive. Once you get teleported back, the achievement will unlock and the Double Feature mode will automatically begin, ending your current game.

Useful Info:
- The Carterizer and Blunderbuss are the best weapons (AK47 is also good)
- The Boss waves are at the end of round 12 and 19
- Purchase Exo-Health, Exo-Reload, and Exo-Medic first. After that grab any others you want to push these farther down in case you get downed by zombies as you will lose the top upgrades first
-There are two sets of teleporters that you can use for a quick escape. One on the rooftop near Exo-Health which goes to the main spawn and another outside of the Spa which goes to the Lounge
- Teleport Grenades can be purchased in the Lounge for 750 and are very useful for quick escape and don't replace your normal grenades
- Contact Grenades can be purchased in the Spa for 750 and are much better than the default grenades
- Save the Supply Drops for the boss waves. You can also enter the second fight in a Goliath (or two) if you time it right
- There are maps on the walls which label each room and show where the current 3D printer is as well as all of the upgrades
- The Spa is good spot to run/jump around and get a train of zombies going
- You have to complete the previous step before continuing and in most cases you have to start a new round. The challenges for example will not begin until a new round starts

Step 1: Shoot 3 valves located beneath Exo Health they will turn blue once done

Step 2: press the panel in the room opened up beneath Exo health twice with x

Step 3: go to the lounge by the door and there is a room where you can decontaminate and hold x follows the same path as Moon for Hacking with the time it took for doors.

Step 4:Get a Goliath suit which spawns round 8-9 and go to the decontaminate room in the Goliath press x on the door and it will open then punch a zombie in the water and stand in front of a valve and press x again it will turn blue . After completing this step you will be on the Drone Challenge once the round will end

Step 5:This is the Drone challenge: This is where you need to find 5 drones they spawn mid round if you miss one you have to wait till the next round same goes for the round ending you will fail. The drone can be found in the spa, reception, lounge, and beneath the exo suit. The next round it will say challenge complete if done successful.

Step 6:This is a capacitor which is next to the upgrade machine (looking straight at the machine turn left and you will see it)beneath exo suits you have to let emp zombies hit you and they will die charging the capacitor it will go to 100. After completing this the next round will have the grenade challenge. In my video I get this done fast by using the dogs rounds due to the high influx of EMP dogs.

Step 7:Grenade Challenge you have to get kills only with your grenades anything else and you will fail the challenge. It will last for one whole round and then it will say challenge complete if done successfully. In my video I show a great spot for coop people.

Step 8:This is the jumping puzzle at spawn you will see a platform which will show simple jumps if you need help watch the video which I will do add soon. Once the final jump is complete it will be disappear and the next round will be No movement challenge. Don't be afraid the game doesn't punish you for failing.

Step 9: No movement challenge. This is where you will lose points based on moving around the map the best strategy for this is to camp in the spa room and run circles in my video were lucky and had dogs but will be different for you.

Step 10: Is the Simon says This is in found in reception to the left of the trophies which show your Easter egg completions. You will need to press x on the blue light then the combination will begin. Which again is like the moon Easter egg simply right down the combination and input and your be on the next step which is friendly fire which happens at the end of the round

Step 11:Friendly Fire if in solo you will see three team mates trying to kill you. In multiplayer I'd suggest you and your team mates split up to complete the challenge you fail if one dies due to team mate fire. The challenge will be complete at the end of the round.

Step 12: The infamous Counter which is found left of the panel beneath exo health from the decontamination step so you need to match the top row with the bottom Now This is going from the left to the right when looking at it directly First Column= Slam Hit Markers, Second Column= Jumping, Third Column=Purchasing Grenades, Fourth Column is Kills on zombies Once they match this will be complete. This will trigger the rocket challenge at the end of the round.

Step 13: This is a rocket challenge very simple just like grenade just get kills without any other weapon and once the round is complete go back to the panel to the right of the counter and follow step 14

Step 14:Very Simple press x on the panel to the right of the Counter (Same panel for the decontamination step )and the teleporter will appear and you press x and you will go to the moon. For coop you will need all 1-4 players to hit the button or the teleporter will not activate.

Step 15: Survive until the game telports you back to the map and your set achievement.
unlocked

Edit:As said in the comments you can get this Easter egg done between round 20-25. A suggestion for when you do the capacitor step 6 try complete the drone step before the Dog round which is 12 as said they will get the box to 75 or higher during those round but this could be due to four players.

SOLO Guide!

This is for completing ALL of Oz's Challenges (plus additional Angie/map challenges) for the Easter Egg on the new DLC Descent.
Below is the video and written guide depending on your learning preference. Enjoy!
This Easter Egg takes time to start because there's some prep work to be done!


Once the game begins activate the generator.

Round 1: shoot zombies 4 times then Knife
Round 2: 7 times then knife
Round 3: 9 times then knife.

I usually stay at the start until the end of round 2! Open up the door to drop down into what I like to call Trident-Land. Grab as many credits off the walls that you can find and turn on the generator in the GREAT HALL. You should have enough points to open up the GALLERIA door, which is where your exo-suit is!

Grab points off the wall and turn on the generator and then turn around and grab your exo-suit! Once you get enough points, open up the door to the TIDAL GENERATOR ROOM (behind the exo-suit up the stairs).

Keep punching the zombies!

Round 3: open tidal generator door, grabbed exo suit, opened Reception Doors.
Round 4: 1st try on the 3D printer.

Once you get enough points, head on over to the RECEPTION DOOR (to the right of you when you drop down into Trident-Land for the first time) and open the two doors. You won't have enough money to do the 3D printer, so punch the dogs during round 4 and you will have enough.

NOTE: During ROUND 5, you will be teleported to OZ. Don't worry, nothing happens this round, so enjoy the sights.

I recommend the BLUNDERBUSS, but any gun right now will do (expect for anything that explodes i.e. Mayhem/crossbow. After doing the 3D printer, head over to the TIDAL GENERATOR Room for the 1st step of the Easter Egg!

Step 1: THREE VALVES.
In the TIDAL GENERATOR Room are three (3) valves that you need to shoot. Your pistol can do one valve before it runs out of ammo and since you completed the dog round, you should have gotten a max ammo. The three valves are located:

a.) ground floor (underneath the staircase to the left of the generator)
b.) 1st floor above the big closed door (right before the staircase leading up to the 2nd floor).
c.) once you reach the last step on the staircase coming up from the 1st floor.

Don't Forget to turn on the Generator on the ground floor, so that you can pick up EXO-HEALTH on the roof. Just keep climbing the stairs until you get outside (across from the teleport machine).

When you shoot a valve until it rotates 360 degress (full circle), a blue light will appear above it. Continue doing this to the remaining two valves until those giant closed doors open!

Once opened, head on inside and activate the computer screen. There will be dialogue and once it stops, activate the computer again and head on out.

STEP 2:
The next step is a two-parter. First we have to go through the RECEPTION area and open the door leading to the ANNEX. Activate the generator and pick up any wall credits. This is the room that has EXO-RELOAD! We now need to open the door leading to the LOUNGE (the door we want is NOT the one across from the exo-reload).

Once you have enough points, open the door and head to the yellowish door that is to the left of the 3D printer. This is the air lock door and the first step. Hold the action button when by the door and when no zombies are near you. This will take a long time, so keep running out of the room and come back when its safe. Your progress is saved, so you don't need to worry about doing this in one swoop. When at last you hear Angie come on the loud speaker that the air lock door step is complete, you need to get to round 8!

During the next few rounds, collect some credits off the walls if you see any, try the 3D printer for the Blunderbuss and distraction drones (they will make this Easter Egg easier) and MAKE SURE to grab the EXO-REVIVE if you haven't already at the top where we started this Easter Egg. In order to get back up there, there is a tube outside the GREAT HALL and outside the RECEPTION area (where we initially dropped down). Enter the tube (IT'S FREE), and you'll be at the top.

When you get to round 8, kill off some zombies until only a few are left. There will be an orbital drop sometime during the round. The drop was a GOLIATH (our final part of this step)! Figure out where it is (whether it's at the top next to Exo-revive or exo-health) and get to it. If you're by the exo-revive and the Goliath is by exo-health, there is a teleport machine by the generator. Hop in it and it will transport you to the other side.

Hold the action button once you find the Goliath, so you can climb in and then take the Goliath all the way to the airlock door. Hit the action button when you get to the door and you will be taken underwater. Swat at the zombie that is blocking your way and keep following the path until you get to a machine under the water. Hold the action button again and the light will turn blue and Angie will say something. Head back where you came from and go back inside. I usually like to blow up my Goliath at this point.

Step 3: Drone Challenge
With the Blunderbuss, this step is a breeze. With any other gun, you will want to make sure they are high powered and have ammo! You need to search the map for six (6) drones (the green spaceships that usually carry something inside). Once you find them, open fire on them until they explode. With the blunderbuss it's one hit! Here are your two warnings:

a.) if you kill all of the zombies during the drone challenge round, the challenge will fail and you will have to continue this challenge on the next round. Remember that higher rounds equal more health for the drones and zombies.
b.) If a drone escapes, meaning it flew away before you could blow it up, the challenge will fail and you will have to wait until the next round.

When you find and destroy all six, the logo on the lower-left of your screen will say COMPLETED! It will tell you instantly, so if it hasn't, you haven't found all of the drones!!!

Step 4: Charge the Batteries (recommend you start BEFORE Round 12!!!!!)

My recommended path for this step and future steps:
Galleria to Annex
Annex to Reception
Reception to Great Hall
Great Hall to (either SPA and stay there or Galleria).

In the Galleria on the ground floor by the GREAT HALL door, will be two things that look like batteries. We need to charge these up with some EMP ZOMBIES (the blue zombies that have blue lightning all around them). Get an EMP zombie close to the machine and let it hit you. The zombie will die and charge the battery. This will take awhile so make sure you are being smart! Don't stand next to the battery. Instead, train in the SPA ROOM around the circular bar area (room where the decontamination zone is and it is off of the GREAT HALL). Once you get an EMP zombie to the head of the line by carefully killing off the other zombies, run back to the Galleria and let the zombie shock you by the battery.

The reason why I recommend you start this before round 12 is because round 12 is usually a dog round. The dogs are incredibly easy to kill and there are a ton of emp dogs, which will make your life easier.

Once this step is completed, Angie will again say something over the loud speaker about charging completed.

NOTE: Keep trying the 3D printer when you get a chance. And if you get the DISTRACTION DRONES, make sure you buy the EXO-Stockpile in the GREAT HALL (outside the SPA room). This will make all of your grenades increase by one. So instead of being able to hold 4 grenades and 2 distraction drones, you will now be able to carry 5 grenades and 3 drones.

NOTE: During Round 13, you will be teleported to OZ again. This time, you need to fight. Find out where OZ is, (he's in one of the four glass rooms on the second floor). When the glass shield raises, open fire on him until the room explodes. Rinse and repeat three more times. At the end, there will be point drops, so collect as many as you possible can! You will then be teleported back.

STEP 5: Grenade Challenge

Super easy and super fun. Head over to the SPA area and grab some CONTACT grenades off the wall if you haven't done so already. You can only use grenades this round, so hop like a weirdo and throw those grenades down below you until the round ends.

Side NOTE: It's ok to use power-ups (turrets, backup, drone) during this step. It will not count against you. Just don't use a Goliath.

STEP 6: Jumping Challenge

Super easy and super fun again (it'll be fun because below is the solution to the hardest jumping puzzles #3 and #7).

Head up the tube to the top of Trident-Land where we spawned and on one side of the platform will be floating blue platforms. Jump on it and jump to the next one. Same goes for #2, but this time you will have to dash over to the center one and the last one in order to make it.

SOLUTION FOR #3 AND #7.
Here are the buttons you need to push to beat these jumps.
start at the back of the platform....
SPRINT
SLIDE (running while pressing )
TAP jump (once at the edge of the platform)
hold jump button (when at the peak of your previous jump)
dash over (hold the left thumbstick in and push forward. You should be able to do this twice).

Same exact steps for jump #7.
The rest of the jumps are straight forward. If there is a platform directly above your head, jump backwards slightly and then hold the jump button and move forward.

If you need to go further then slightly, tap the jump button to jump off the platform and then hold the jump button for height and then dash over to the platform you are trying to reach.

SIDE NOTE: I recommend you complete this jumping challenge before the start of ROUND 20, because you will be teleported to OZ again and if you aren't done, that's just one more round that is wasted when you get back to Trident-Land. Your progress will be saved though, so you just need to continue where you left off.

If round 20 happens, here is how you defeat OZ. Run around the outskirts of the room and activate the four power generators. Once done, run to the middle of the room and activate the decontamination area when OZ is next to you. Start firing afterward. When you see him start to recover, you just need to rinse and repeat the previous step.

IMPORTANT NOTE: Not that my other notes aren't important, but I wish I knew this one before! If you activate all four generators and then activate the decontamination area when OZ is NOT there, you will need to activate all generators again! Just beware of this!

Step 7: Move Challenge
This challenge is simple if you have the right power-ups. This challenge requires you to not move as much as you would like to. The more you move, the more points you lose. The less you move, the more points you get to keep. Don't lose all of your points though, because then you will fail (and die). I usually throw down my reinforcements power-up and my drone as well as my distraction drones. I never have to move!!

Step 8: SIMON SAYS

Clear out the next wave of zombies until three crawlers are left. Three is max, two is ok. Head over to the Reception room via the GREAT Hall. To your right as you enter, will be four computer screens. Activate the one that is glowing and start playing simon says. The final pattern as eight (8) numbers, so if you need help, pause the game and write down the order as you go. I recommend you number the computers 1-4 from left to right. Once the crawlers make it into the room, you will need to back up and dash forward to activate those computer screens in the correct order. Once completed, Angie will announce it on the intercom.

NOTE: If you get to the computer too late while playing simon says, it'll start over and with a different pattern!!

Step 9: Friendly Fire Challenge
This is adult duck-duck goose. There will be three random characters trying to catch you. Don't let them. You cannot kill them and they will always go after you. Move from room to room trying your best to complete the round as quickly as possible. Activate your power-ups if you have any. I once activated invisibility, but the characters were still shooting at me, so just be aware of that. Once the round is over, the challenge is complete.

Step 10: The BOARD
We will need the EXO-Slam for the next step. Head over to the TIDAL GENERATOR room (room where we shot the three valves). Just before entering the room, turn around and there will be the exo-slam machine. Purchase it! Climb the first set of stairs once in the tidal generator room and go into the room that was once locked. In the room with the computer that we activated earlier, will be a giant board with numbers. You need to match the BOTTOM numbers with the TOP. The order is as follows:

Far left: Exo "butt" slam (double jump and hold the crouch button while in the air)
Next to the left: Jumps (literally just tapping the jump button will count as one number)
Next: Grenade purchases (you need to purchase grenades off a wall. I recommend going into the SPA room for this)
Far Right: Kills. (how many zombies you need to kill.

Note: If you accidentally go over the number on the top, don't worry and just keep going. The number 9 will revert back to a 0. I recommend going for the slams and grenade purchases first.

Step 11: Rocket Challenge
This is the exact same challenge as the grenade challenge, only this time you have a Mayhem MK 25 in your hands. Jump around in the SPA area and launch rockets at the groups of zombies. Once the round is over, this challenge is complete.

NOTE: The Mayhem will decrease your speed and you won't be able to throw any distraction drones. You still can use power-ups, though!

Step 12: Memories
Head back to the computer in the TIDAL GENERATOR room and activate it. You will hear OZ talk, run to the teleport machine right next to the computer and you will be teleported automatically.

This is the final step. TRAIN. TRAIN. TRAIN. Around the bus. The zombies that spawn will be focused on your teammates, so use that to your advantage. Throw down some distraction drones, activate your power-ups, and unleash your ammo. After two rounds of zombies (don't worry, it's easier than you think), you will be teleported back and the game will end! The 50G Renion achievement is now yours!

I haven't seen a very comprehensive or clear description to complete some of the steps on a guide yet (Especially the jump challenge) so here is my very in-depth guide.
Check it out and good luck!

First off your going to want to have 3-4 players to get this achievement as it makes it much easier. You can do it solo but with this Easter egg it is much harder to do it solo. Text Guide will be below the videos Enjoy!

Part 1:

Part 2:


Text Guide:

Step 1: You want to make your way to the Tidal Generator room and shoot the 3 switches you see in the video and shoot them until the light above them turns blue. After you do this doors will open up where you can go and activate the computer by pressing .

Step 2: After that you want to go to the lounge area and go to the door you see in the video and hold over the handle to depressurize the room.

Step 3: After you have depressurized the room you can to wait till round 8 where a Goliath will spawn on either the spawn area of the exo health area. You want to take this Goliath and bring it to the room that you depressurized. Hold on the door and it will open up for you once your in the Goliath. You want to make your way through the water and punch the floating zombie out of the way and go activate the button ahead by pressing .

Step 4: After that the next wave should be the Drone Challenge and you want to camp it out in the Spa room until you have 3 zombies left. Let one of your partners kite the zombies while the other 3 with strong weapons go around and find 5 drones that need to be destroyed. After you have destroyed all 5 you can end the round and the challenge should be complete.

Step 5: You want to make your way back to the exo room and in the corner you should see 2 generators that you will now have to charge with exo zombies that electrocute you. This process should only take 2-3 waves and is easy.

Step 6: Next after you complete charging the 2 generators the next wave should be the Grenade Challenge. All you have to do is complete the level only using grenades and you have unlimited contact grenades.

Step 7: After that round make sure to keep 3-4 zombies next round and then have one player good with jumping go to the spawn area. Here they will find blue platforms and have to complete a series of jumping challenges to proceed with the next step of the Easter egg.

Step 8: End the round and the next round should be the Move Challenge. During this round you will lose money if you move. If you hit zero then you wont be able to move until you gain more money. My group just camped it out in the Spa Room until the round was over.

Step 9: On the next wave you want to have some one kite 3-4 zombies while one person in you group goes to the promenade area where the box is. Here you will find 4 computers and if you hold on the third from the left computer and it will start a little mini game of Simon Says. All you have to do is complete the game.

Step 10: After Simon Says the next round should be the Friendly Fire Challenge. All this does is make this round have friendly fire turn on. Just make sure you don't shoot each other and you'll be fine.

Step 11: Next you want to make your way to the Tidal Generator room and here you will now see a panel with numbers on them. The far left one indicates exo slam kill. Second from the left indicates your whole team jumps. Third from the left indicates purchases off the wall. And the far right one indicates just kills in general.

Step 12: The next round should be the Rocket Challenge. You are given the Mahem Mk25 and all you need to do is finish the round. Simple as that.

Step 13: After that you want to make your way back to the Tidal Generator room and everyone has to hold on the computer. (Make sure if your playing with others that all players hold on the computer or you wont be able to teleport even if their dead) Then everyone will be teleported to a new area with a bus in the middle and you will have to fight off two waves o zombies. After that you done and have completed the Easter egg Congrats.

coreymawf's solution (Solution for Reunion In Call of Duty: Advanced Warfare) breaks down the necessary steps, but I wanted to add a few other pieces of advice, based upon my ~30 hours of attempting this. A good run will take anywhere from 1 hour 40 minutes to 2 and a half hours, so be prepared for a long grind.

1. This is easier as a 2-player team. With three players, the amount of zombies increased dramatically and with 4 it is easy to be overwhelmed. It's also an important factor for the next item:

2. The Blunderbuss is essential; if one of you don't get it in the first few hits, restart. The Blunderbuss becomes a critical item in defeating Oz in Round 20, but also for the Drone Challenge. Exo Reload is also essential with the Blunderbuss.
- Seriously, make sure one of you has the Blunderbuss. Even with another Wonder Weapon (CEL-12, Trident) or an S-12, the Blunderbuss will be your key to surviving.
- You will want your Blunderbuss to be at least at Mk 8 before Round 20.

3. The earliest you will be able to start the Drone Challenge will be Round 9.
- Before starting the round where this challenge starts, have all players start in the spa. Reduce the zombie horde down to 6-10, and work as a group to track down each drone.
- With a Mk 2 Blunderbuss, you can destroy the first 4 (of 5) drones with one shot at point blank range. The fifth drone usually requires two hits.
- If you don't have this complete by Round 11, restart.

4. For the Capacitor Challenge, thin down the number of zombies until you mostly have EMZ's left, then use those. You will likely need 3, maybe 4 rounds to complete this challenge. If you don't have this complete by Round 16, restart.

5. For the Jumping Challenge, be aware that each jumping pad has a very thin border that starts green before moving to yellow and finally red. This all takes place within about 3-4 seconds, but you will have a little bit of time to readjust your position to jump again.

6. Having Sentinels are invaluable for Round 20 if you start to get into trouble, but for the Memory Simulation Rounds they make the rounds much easier (they can also revive one of you if you're downed). Be sure to pick them up but to keep them toward the endgame. Camouflage and the Assault Drone are also helpful.

7. For the Rocket Challenge, be aware the the Mahem Mk 25 has substantial splash damage; you need to fire away well away from you.

8. Once you finish the Rocket Challenge, it will be tempting to begin the final step straight away when the next round begins. Do not do this, as you will be overrun almost straight away. Run through most of the next round and get the zombie count down to a low and manageable number, well away from the secret room (i.e. Spa or Reception). Once you have matters under control, run back to the secret room and initiate the computer and teleport machine.

9. The key to the Memory Simulation Rounds is to just stay alive. The round counter will not increment, but the first "round" will end when all the zombies disappear and Oz starts his speech. Shortly after this, the next round of zombies will appear.
- Run in slow circles around the bus. With your AI assistants (who are moderately helpful) and your Sentinels (very useful, as they can revive you), you will not be overrun.
- You can fall off the edge of the map, so be mindful of straying too far from the central area.

Once you complete the second "round", more dialogue will ensue and you will teleported back to the main map. The game will end soon after and the achievement will unlock.

(Negative voters: your feedback is appreciated if you believe this can be made better.)
