Call of Duty: Black Ops

Step 1
When the power has been activated, you'll need to play a round of "Samantha Says" on the four computers in the outside area near the beginning.

--------------------------------------------------------------------------------

Step 2
Next, work your way to the labs. Here search for the "Hacker" nearby on one of the counters. Using the hacker, hack either one of the four red buttons along the wall. This will activate four switches nearby as well. You can locate them by searching for their green light that should be on by now.

--------------------------------------------------------------------------------

Step 3
Now you need to hack all four of these switches. Once this has been accomplished, the four buttons you found on the wall earlier must be pressed in less than 2-3 seconds. When done properly, they will stay lit. This will open up the round hole in the pyramid front graving. Of course you'll be needing this for another step.

--------------------------------------------------------------------------------

Step 4
When tunnel 6 has been breached, have someone hack the proper terminal from the Receiving Area so that the Digger leaves.

--------------------------------------------------------------------------------

Step 5
Go back safely to tunnel 6 and see that a Black Egg has appeared near the M16. Knife it and you'll see it moving around the room. Follow it since it will get stuck in various places. Knife it again and open doors for it until it flies up onto a dish on top of the spatial base.

--------------------------------------------------------------------------------

Step 6
Have someone use the Wave Gun on the tip of the Dish. This will cause the Egg to move again. Follow it through tunnel 11. It will go hide into some metal railing at some point. You can either shoot it from the wall next to Stamin-Up of throw a grenade at it. Keep moving it until it reaches the pyramid in the power room. It will fit in the hole you just opened.

--------------------------------------------------------------------------------

Step 7
A tubular container will rise up from the right side of the pyramid. Next step consists in filling up this container with Zombie Souls. Kill around 25 zombies near the container. You'll see the souls flying up to the ceiling structure which will fill up the tank.

--------------------------------------------------------------------------------

Step 8
Once filled up entirely, you'll hear a sound. Activate the switch right next to the container; this will open the pyramid, revealing Samantha.

--------------------------------------------------------------------------------

At this point you will be awarded a Death Machine for 90 seconds. As well as the achievement "Cryogenic Slumber Party" unlocks.
This is only the first part of the Easter Egg. There is still another achievement to unlock! Starting from here is the part where you absolutely need Richtofen's Vrill Generator to proceed!

Just a few side tips to the above solutions,


- When you start the hunt grab the hacker in the room just up from the pyramid hack the upper door leading to the top level then the door to no mans land and the one opposite which leads to the dome...once inside the dome hack the door on the other side...it means you can now reach the teleporter from the dome (you wont need your space suit on throughout this only if the area has been breached and the decompression has begun)....this all saves you money on doors and you need to hack the walls anyway so it makes sense to use it on the doors.



- If the first excavation is not in tunnel 6 it maybe best to restart as it could take alot of waves before it goes to tunnel 6 making life alot more difficult to survive its random sometimes it starts in the tunnel 11 sometimes in the domes and so on...ideally you want it to begin where you need it which is tunnel 6, make sure all doors near the ball are open so it can pass through without trouble.


- Before you start to fill the jug with the souls its best to buy Claymores from the Dome and place them around the pyramid to keep the zombies that end up round the back of you away...trust me it helps alot.


-At the very start remember weather the perk by the teleporter is Juggernog or Speed Cola which ever it is at the start the moment you teleport back to Area 51 it will be the other and so on...so Jugg - Cola - Jugg...


- Do not let the Spaceman grab you while you have any perks as his likely to take them weather he downs you or not....think of him as a cross between George and the Pentagon Thief...




Good places to hold down when surviving waves-

No mans land. close to the teleporter and you have space to round the zombies up.

Dome - lots of areas to run around and near the teleporter



Hope these tips help but any questions feel free to ask.

I want to add, I havent seen it posted anywhere, but you dont need to do steps 1 and 2 for step 3 to happen.

In other words, you dont have to do the game and hack the terminals for the "Black Egg" to appear. As long as Tunnel 6 is breached it will drop it as happened to me today. So it could be easier to wait for the egg to drop, then start the steps.

Got this achievement lastnight it was great...

#1
NOTE: THIS IS IMPORTANT SO REMEMBER NOT TO USE ANY EXPLOSIVES WHILE NEAR THE WINDOWS ON THE MOON IF THEY BLOW UP YOU WILL DEPRESSURIZE THE ROOM CAUSING IT NEAR IMPOSSIBLE TO HACK THE COMPUTER IN THE LATER STEPS...

#2 Once the power has been activated, one of the four players needs to play a round of "Samantha Says" on the four computers in the outside area near the beginning (In between the M14 & Olympia)

#3
Next, work your way to the labs. Search for the "Hacker" nearby on one of the counters. The hacker is very useful you can hack windows to rebuild them, hack doors to make them only 200 points to open, Hack perks to buy all the perks for the achievement "Perks in Spaaaaace!", Hack teammates to give them points, Hack a box that has activated to et one random gun but you can only do this once per box, and of coarse the most important to hack either one of the four red buttons along the wall. This will activate four switches nearby as well. You can locate them by searching for their green lights.

#4
Hack all four of these switches. Once these has been hacked, you can find four buttons on the wall lined up next to one another have all four players press them at the same time. They will all stay lit when done right. This will open up the round hole in the saucer in front of the pyramid.

#5
The alarm will go off letting you know tunnel 6 is about to be breached, have someone hack the proper terminal from the Receiving Area. Note this could happen at anytime if you want to get the "Ground Control" achievement hack the terminal before the Digger brenches if your not able to get there in time dont worry even if it breaches you can still continue with the Cryogenic Slumber Party + the Big Bang Theory Achievements.

#6
Head back safely to tunnel 6, you'll see the Black Egg has appeared near the M16. Using your Knife to move it around the rooms make sure you have nearly all the doors opened plus you need a Ray Gun & Wave Gun to help move it. Follow the Egg since it will get stuck in various places. It will get to the Recieving Area Outside near "Samantha Says" till it gets stuck up onto a dish on top of the Base. Have someone use the Wave Gun to tip of the Dish and drop the Egg. It will begin to move again. Follow it through tunnel 11. It will go hide into some metal railing at some point. You can either shoot it from the wall with the Ray Gun next to Stamin-Up or throw a semtex grenade at it. Keep moving until it reaches the pyramid in the power room. It will fit in the hole of the saucer. If you've gotten this far your doing well and about to recieve the Cryogenic Slumber Party Acievement which is the first part of the Big Bang Theory.

#8
A tube container will rise up from the right side of the pyramid. Next fill up this container with Zombie Souls. Kill 25+ zombies near the container. You'll see the souls flying up to the ceiling which will fill up the tank. Once filled up entirely, you'll hear a sound. Activate the switch right next to the container; this will open the pyramid, revealing a Hologram of Samantha. At this point you will be awarded a Death Machine for 90 seconds. As well as the achievement "Cryogenic Slumber Party" unlocks.

NOTE: THE RUMOR THAT ALL 4 PLAYERS HAVE TO HAVE THE OTHER 2 EASTER EGGS FROM CALL OF THE DEAD AND SHANGRI-LA IS CRAP. I DID NOT HAVE THE ACHIEVEMENTS FROM THOSE 2 AND AND I WAS RICTOFEHEN AND STILL GOT THIS ACHIEVEMENT...SO NO WORRIES ACHIEVEMENT HUNTERS!

BIG BANG THEORY: (Need Gersh Devices & QEDS)

#1
At this point you have Death machines I suggest, but its not required teleport back to earth with your Death Machines and farm some points...tho you need to teleport down to Earth anyways to start your first step for this achievement. In the right corner you will see a shelf with two Hexagon Plates throw grenades to knock the plates on the floor afterwards throw a Gersh Device to suck up the plates onto the teleporter with you...teleporting back onto the Moon the plates will be next to Quick Revive. Use the QEDS to teleport the plates onto the stand.

#2
Have one of you teammates grab the crooked pipe from one of the three room that you had to hack the green lights...it is usually under a computer but might change locations. Bring the pipe back to the Recieving Area and place it between the plates and the computer to the right of the plates holding (X). Have whichever player that is Rictofehn place the Golden Rod in between the plates holding (X). The computer screen will be Red keep tapping (X) rapidly till it turn Green as soon as it turns Green have Rictofehn ready to pick up the rod by holding (X).

#3
Have Rictofehn head back to the Power Room and place the Purple Glowing Rod in the Saucer in front of the Pyramid. The 4 ner tubes will rise you then will need to fill all these tubes with Zombie Souls depending on what round you are it should take 2 ounds to fill all the tubes, but remember you have to hve the zombies cloe enough to the tubes to fill them but so hold in there. Once all the tubes are filled a sound will go off letting you know that the switch needs to be flipped. Once flipped whoever is Rictofehn needs to go to the Saucer and remove the Rod which will give whomever is Rictofehn all 8 perks in the game. Lucky him/ her...

#4
At this point whoever has QED need to throw one at the saucer...note: You need to have it explode right on the saucer so it teleports the Egg. I would suggest laying prone in front of the tanks facing the saucer, but its up too you. Once this happens run down to "Samantha Says".

#5
The Egg should be to the right of "Samantha Says" use a Gersh Devices to pick the Egg up. Afterwards have a player play "Samantha Says" 3 times each time you win a Rocket will raise up after the 3 game is won the Rockets should take off and blow up Earth...Congrats you got the "Big Bang Theory" Achievement is yours plus every player gets all 8 perks and the best part they are all permant if you GO DOWN/ DIE/ OR EVEN IF YOU FRIEND THE EVIL SPACEMAN GRABS YOU all 8 perks are yours....so Congrats you got 100 GS.
