How to unlock the Death Ray achievement in Call of Duty: Black Ops III - Definitive Guide

In order to get this achievement you must use any of the 4 Corruption turrets that are spread out across the map in these locations: Spawn area, Der Eisendrache, Verruck, and Mob of the Dead. In order to use these turrets for the people who don't know you have to start the corruption generator at any of those location and kill the enemies that come towards it such as Keepers and Fury's. An easy way to get this achievement is to have multiple people in 1 game and stand behind the turret after gathering a large group of zombies towards the turret (Note you have a short time to be on the turret so make sure you're ready to get on it when you see a large horde of zombies).
You can do it in solo play but it may take you a while to get it. I did it solo and got it at round 35.
Here are some video to show you how some people did it in multiplayer (like how PowerPyx did it) and how I did it in solo play (Sorry for the pixelation on my video I streamed it from the twitch app on Xbox so you won't see me get the achievement as well).

Coop method:

Solo play method:


Note: The reason I say it's easier to do it with more people is because of more zombies per round and the fact that zombies spawn faster the more players that are in the game.

I just want to chime in here for anyone going for it on solo. The magic number is Round 31. I tried 29 and 30 and couldn't get it. I nailed it on Round 31. I ran my train in the Mob of the Dead for anyone curious.

ox BlackJack xo it doesn't matter how many people are in the group it's just the thing of the more people in the game equals faster spawn rate. The video I posted just shows how it might look like in coop

I think so but I've never tried it on anything besides zombies. Keepers, Fury's and Parasites should count towards the achievement. I don't know about margwa's or Panzer Soldats.

Heads up to all going for this; don't try it at the castle (eisendrache) it doesn't seem to work. I tried on solo every round from 35 to 42 and it wouldn't work. Made my way to verukt and got it first try... I'm 99% sure the castle turret won't register it. Just an fyi

I've helped 2 people get this and in my experience we had to go to round 40+ to get the achievement. My successful attempt was Der Eisendrache round 44 with 2 players. The other guy in that game got it at the same turret at round 39. Then yesterday I helped some one again and we went to round 42 with 3 players and did it in Spawn. It took more then 20 attempts in Der Eisendrache and Spawn. Every thing has to fall in to place. So just keep trying.

Round 37 solo here. Mob Of The Dead seems the best to train the horde. At round 37 I was just spinning in circles on the turret as they were spawning like crazy all around. Good achievement and great challenge.

Damn, this one really sucked. Started trying for it on Round 30 and didn't get it until 39. Honestly wouldn't even recommend going for it until 35. Just glad to get it in the end though.

Just did mine on round 38 solo. Had the thundergun, Apothicon servant and dingo all pack a punched. Used soda fountain, round robbin, power vacuum, and after taste and extra credit gums. Trained in Kino on the stage and used the protector to get up to round 35 when I started. Unsuccessful until round 38 where I ran my train to the corruption turret in front of the pyramid and threw an arnies right in front of the turret and went to town.

Did it co-op in round 34, just be careful that Arnies eat the zombies so it may be possible in the early 30s without one.

Just did this achievement tonight. We had 4 people and our first person was able to get the achievement on round 17. The next on round 21 and the next on round 25. We died out before the fourth guy could get it so we did a second game. We were trying multiple times each round but unfortunately it seems very inconsistent with how many zombies come.

Wave 46 solo - did it at the Mob of the dead turret. Tried about 15 times at DE, but no luck, also just before jumping on the turret, I whacked my sensitivity up to 9 on Horizontal and Vertical and that really helped me.

This is already an old game, but I just went for it and got it on 38. What matters is spawn RNG in the later rounds. That's why some of you got it in different places. Sometimes the zombies just don't spawn in the right spot at the right time.

But THE MOST IMPORTANT THING that nobody is mentioning is that if you play on a lower sensitivity, YOU HAVE TO INCREASE IT when you jump on the turret. I just play on default and have since forever and I've soloed Moon, Gorod Krovi, and so on, so I am a good player. But the turret doesn't move fast enough to protect your ass when you're on the turret unless you crank your sensitivity. Your shield seemed to just disappear while you're on it as well. I personally used an 8 sensitivity when I hopped on the turret and just switched back when I got off.

Obviously this applies to solo as I'm sure your buddies would cover you otherwise.

Hope this helps someone.

Round 33 on Mob turret also. I think there are 5 spawns to watch after you shoot your horde.

Assume you're facing 12 o'clock when facing the cell block, with the portal behind you at 6 o'clock:
1. 3 o'clock, immediate right, coming over the rocks of the corruption engine.
2. 2 o'clock, window barrier on the right, below where you can drop down from the walkway.
3. 10 o'clock, window barrier on the left, under the walkway and stairs.
4. 10 o'clock, but tucked further in to an alcove. If facing the gobblegum machine, it's beyond and slightly left.
5. 11 o'clock, in the back of the ground floor. If facing the gobblegum machine, it's on your immediate right.

While the zombies are easiest to see coming from #2, there should be 3 groups spawning from the left hand side. I would do quick sweeps across #2 & #1 (seems like you can get lucky and tag some zombies climbing over #1 without them being fully visible yet, as well as those that haven't climbed over/through #2 yet), but then do some more concentrated spraying around the straight staircase at your 11 o'clock. Zombies from #3 & #4 should be to the left of the stairs, and I tried to see if I could shoot through the stairs to reach any zombies coming from #5.

Let me preface this guide by saying: F*CK THIS ACHIEVEMENT! It is incredibly frustrating and a huge commitment to do, despite it being relatively simple in theory.
The basic idea for this achievement is to kill 40 enemies (they don't need to be just zombies) with a single activation of a corruption turret, the corruption turrets are controlled by you and insta- kill enemies. They only last about 25- 30 seconds, so you don't have a ton of time to do this. The problem with this is that you will never have an instant where 40 enemies are on the map at once, because the game caps the number of spawned zombies at around 25. So to get this you need to kill a full group of 25 zombies and then get an additional 15 or so to spawn in before the timer on the corruption turret runs out. This is much easier said than done. On earlier rounds, this is basically impossible because the zombies are not all running, and spawn in slower than at later rounds, and even so, on late rounds it is quite a challenge to get enough.

I'll detail how I did this, but first I'll explain how to unlock a corruption turret, if you already know how to unlock pac- a- punch skip this because a corruption turret becomes available every time you finish a generator, and can be purchased same place you activated the generator.

Activating a corruption turret

There are a total of 4 of these guys around the map, and as soon as you unlock one it is available for use, so you do not need to do all 4.
There are these things called corruption generators around the map, they are incredibly obvious and look kind of like gates to hell. If you don't know what they look at, spawn into the map and run to the other side of spawn and you'll see one, very hard to miss. The 4 locations are:
-Spawn
-Mob of the dead
-Verruckt
-Der eisendrahe

To activate any corruption generator, head to the back side of the pedestal type thing in the center and spend 500 points to activate it. This will begin a sequence where either keepers, furies, or both will spawn in and start attacking you. You need to survive for about 15 seconds before all these enemies die, whether that means shooting them or just running around avoiding them is up to you, this is very easy to do so you'll have no problem.
Once the generator is finished, you are awarded with 1000 points and can now buy the corruption turret here for 2000 points at the same location you activated the corruption turret.

Doing the corruption generator provides power to its respective island, which is necessary for getting anywhere on this map.

Making the rounds

Now, unfortunately, due to the nature of the zombies slower spawn rate on lower rounds, you will need to be at a quite high round to even attempt this. I would not even try it until at least round 30, I personally got it at round 38. If you're relatively inexperienced at zombies getting to these rounds can be quite difficult. Here are some tips to help you out.

Your perks can be largely up to you, but you will absolutely need juggernog and quick revive. Also, if you did not know, once you have 4 perks you can get a free random perk by doing this wall running thing at der eisendrache.

I recommend you have either a thundergun or apothican servant, and an upgraded brecci in terms of weaponry. To upgrade the thundergun is just like any other weapon, but the apothicon servent is different, and can be a little tricky, so you may want to just stick with the thundergun if you're not sure. You will also want lil arnies from the box, which you should spam out if you see a max ammo before you grab it.

The zombie shield is also very helpful as it prevents damage to your back, so you will want to build that as well, it it quite easy.

The main area you want to train at is kino der toten. This is actually a very good training spot and even relatively inexperienced players could manage.

So in between round 1 and 30 you want to:
-Have gotten 4 or 5 perks
-Obtained a brecci, thundergun/ apothicon sevrant, and lil arnies from the box
-Built and equipped the shield.

Obviously, none of this is required for the achievement, but considering it requires you get to such high rounds you want to make sure you're well equipped. You should easily amass a ton of points before you actually start this achievement so, feel free to grab any nukes you see as you want to get there as quickly as possible.

Actually getting the achievement

Once round 30 rolls around you can get started. Please note that this is a SOLO strategy, which is how I did it, it is actually made quite a bit easier with more people, and I'll explain how to do that later.

Once round 30 starts, first make sure its not a parasite round (obvious by the map changing colour). If it is, get through that (just spam out lil arnies, might as well because you get a free max ammo at the end). If it's not, you can get started. Train up the zombies in kino. If either a margwa or panzer spawns, kill them immediately (they do not spawn very often). As well, try and use your brecci to kill and furies you see, this is because the furies knock down zombies as they walk, which slows them down and cause them the respawn (you don't want this). Once all the zombies have spawned in, slowly make your way to der eisendrache from kino. You don't want to outrun the zombies, you want them to stay close by so they don't respawn in front of you.

Now you may be tempted to try using the der eisendrache turret, as it is right there. While this may technically work, I must have tried 30 odd times on this one and couldn't get it, I assume because the spawn rates are too slow in this area. Instead you want to go to the turret at mob of the dead, I got this my first try when I did it here (to be fair I was on quite a high round).

Head through the portal behind the der eisendrache turret, and wait in nacht for a few seconds until the zombies behind you start to go through the portal, now head to the other end of nacht and through the portal to mob of the dead. Again, wait until some zombies follow you through.

Now you don't want to jump on the turret right away, as some zombies will have respawned, so you want to group them all up again. I suggest you bring them over to the cafeteria and run them through there, allowing more to spawn in. This is a very treacherous area so you need to be careful, as a full group of zombies could easily overwhelm you. You will need to kind of bob and weave through recently spawned in zombies as you leave the cafeteria, which is quite tricky, if you get scared, don't hesitate to pull out your thunder gun or apothicon servant to save yourself, and just head back to kino to try again. Now once you leave the cafeteria, a full group should have spawned, so head over to the turret and buy it.

The turret is on a timer, not based on ammo so hold down the trigger the entire time. Kill the full group behind you and just spray at anything that moves. You are not invulnerable while on the turret, and zombies will spawn behind you, so every few seconds do a quick spin around to kill anything that might attack you. Shoot at every single zombie you see until you are kicked off and you just might get it, but understand that it is unlikely to happen your first time.

As soon as you are kicked off head back through the portal behind you and run back to kino, trying again next round. Solo, this is very difficult and requires a large amount of luck, if you have people to play with, it can be made much easier however.

Multiple people strategy

As with solo, you will want to reach about round 30 before trying this. The difference here is that the spawn rates increase quite a bit with more people, so it is much more feasible to get 40 in the limited time you have. The people not going for the achievement will want to buy widow's wine, as they are kind of acting as monkey bombs for the person doing the achievement, and they need to stay alive themselves.

Have everybody training zombies at different points on the map, but relatively close to the der eisendrache turret (where I recommend you try this). Bring your zombies to der eisendrache at around the same time. Now, once all the zombies are there, the guy going for the achievement needs to quickly jump on the turret and shoot everything he sees. The other guys should stand a few meters in front of him, so the zombies spawn in and attack them (try and kill the zombies before they kill the other players). As with the solo strat, make sure you watch your back as well.

I can't personally speak the effectiveness of this strategy, as I never tried it, but if you are in a game with decent zombies players, this should be much easier than solo.

No matter how you do it, this achievement is terrible. Quite a bit needs to go right for you to get it, and it takes a fair amount of skill. I personally spent 15+ hours just on this achievement trying it solo, so hopefully you have better luck then I do.

There are 4 corruption engines across the map (Spawn area, Mob of the Dead, Der Eisendrache and Verrückt). There is an achievement for getting 40 kills* with a single use of one of the 4 death rays. These death rays spawn after you've successfully overridden a corruption engine. *= even though the achievement states 40 kills I'm more than convinced you actually need to kill over 40 zombies with a single use of one of the corruption engines. 2 main things to take into account here: The higher the round, the easier it is. The more players the easier it is. The best area to go for this achievement is in my opinion in Der Eisendrache, though I think Mob of the dead is pretty decent as well. The main issue here is the amount of zombies which you can kill in the single duration of the death ray. You will want to get to a high round first, as more zombies will spawn in higher rounds and they will respawn faster. Also playing with more players will result in both more zombies spawning and a faster respawn time. Each round has a maximum amount of zombies which it can have in the map at any given time, and a maximum amount of zombies which will spawn during the entire round. E.G. round one has 6 zombies when playing solo, all of which can spawn at the same time. Playing with 4 players will result in 12 zombies spawning in round one, 10 of which can spawn at the same time. Upon killing one or more of these zombies, more will spawn until the maximum of 12 is reached. Killing zombies then will not result in extra zombies spawning, unless a new round is started. These amounts will, as mentioned, increase as you progress through the rounds. At round 25, there is a cap of 25 zombies which can be in the map, regardless of the amount players being in the game. My advise would be to try from round 25 on to get this achievement, preferably with more than 2 players. Gather a train of zombies until you are sure that they don't spawn anymore. Then make your way to the death ray, have all other players stand behind you. Then activate the death ray when the zombies are getting close and preferably, you can see all of them. Then finish off the entire train of 25 zombies and keep killing them quickly as they spawn. The death ray only lasts for 25 seconds or so. Keep the laser firing at all times as there is no such thing as it overheating. Also don't pick up any carpenter pick ups and don't rebuild the barriers in the direct proximity of the death ray. You want the zombies to reach you ASAP! Keep in mind that there is a reason that a lower amount of gamers (10 %) have got this achievement than the amount of gamers who have done easter egg. It is a tough one to do and requires patience and luck!

Apparently you can do as early as round 35 on solo but I failed on 75 and 77 and got it on 81.

I chose to go to mob of the dead because out of all the turret locations this one is the tightest. At the start of a new round I threw an upgraded little arnie, then used the turret to kill the distracted zombies. Make sure you have widows wine as you will be attacked from behind while on the turret.

This is the hardest miscellaneous trophy in the new map. It is incredibly difficult to do solo, so I recommend doing this one in co-op.

The Corruption Turrets are the same things you activated to unlock the portals to Nacht. They cost 2000 points per use, and they don’t last very long. You need to kill 40 enemies in a single use of a turret. It might not sound like a lot, but it is actually quite difficult.

The game does not spawn an unlimited amount of zombies at once, it maxes out with 24 zombies spawned at any given time. So you need to first be on a high enough round where enough zombies spawn (I recommend round 25+), and also you’ll need to have as many zombies on screen as possible before starting the turret.

There are turrets at the flowing locations:

  • Spawn
  • Mob of the Dead
  • Verruckt
  • Der Eisendrache


I personally recommend using the one at Der Eisendrache, as enemies cannot spawn in behind you while on the turret, so you only need to aim straight for the kills. Others have reported that the one in Mob of the Dead is another good choice since the spawns are all in plain sight. But there is one spawn on the right side of the turret, so be careful if you use that one.

If you are playing co-op, have the one going for the trophy camp near the portal and have another run a train in front of the turret. Then the person running the train can bring the zombies right to you as you activate the turret. They can also watch your back if a zombie somehow spawns behind you.

First you need to hack at least one decomposition cannon . But if you do this solo, you can get 40 kills on wave 35+. Below is problematic.

And when there are a lot of zombies, you need to activate the cannon (2000 credits) and burn 40 zombies in one go. (Just touch a zombie with a shot)

If you play solo, then below 38 waves you don’t even have to try. It’s most convenient to do it on a pyramid, as you can run in circles and gather a crowd

From wave 25+, the maximum number of simultaneously present zombies will be approximately 25. (even if you play solo or in co-op). Beam operating time is 25 seconds. You will have to act quickly in order to have time to destroy the main backbone (25 pieces) + 15 zombies, which should be reborn by this time. A good place, as Der Eisendrache ("pyramid") was written above. It is better to activate the beam when weightlessness (gravity) ends, as it slows down the zombies. Don't take the "CARPENTER" bonus.

Made a solo trophy on wave 35 of Mob of the Dead. To my surprise, it’s a very convenient place to dance zombies (I walked slowly around the perimeter counterclockwise) and the area is open, although no one writes about it. The only dangerous place for zombies to spawn is next to the turret - exactly to your right, if you stand behind the turret, you need to look there.

It is advisable to play 3 or even 4. When there is at least wave 30, one person (who needs the trophy) drives zombies to a location with a pyramid and gravity (without killing anyone). The other two are trying to escape from the zombies through the catapults (the player kills all the zombies nearby and jumps through the blue catapults). This must be done until two players have no zombies. If they are not there, then all 25 pieces are in the hands of the player who is driving. When ready, two players approach the third through the center of the map (Natch der Toten), and at that moment he begins to kill zombies from the front using a beam. If there is a chewing gum “Here I am” (opens after level 34) or one of the players has an “Arnie” grenade, it is advisable to use it behind the shooter, all the zombies will be much faster to meet this gun, which will have a greater chance of getting a trophy.

I went solo. I started making the trophy from wave 36, but I only managed to get it on wave 42. If you don’t take percoholic chewing gum, then you need to take health, resuscitation, a perk for three weapons and widow’s wine. To comfortably reach wave 40+, you need to draw a weapon - an electric weapon (pump up), Astot of Estulla (pump up to Estum-Ot) and a Rift E9 pistol (or something that takes out quickly). Also draw out Gravity spikes and Arnie (it is also advisable to pump them up). You can take a wolf's hat to make the run longer.
Tactics - on waves 15+ I stood with my back to the jump rope or teleport (right at point-blank range, so that the next step back could be immediately knocked down), killed zombies if I saw that they were breaking through, step back and already in another location and run to the next such point (you can call for an assistant ). And so on until wave 42.
I chose the widow's wine perk instead of double shot because... when sitting down at the turret, I didn’t have time to rotate the turret around its axis if they started pressing from the side, with the widow’s wine perk it’s not scary, because they slow down after impact and you can easily incinerate everything around you.
I did it in a location with a pyramid. After the start of wave 42, he got the crowd running around (you can kill if someone gets in the way and you can’t run around him), waited until the weightlessness passed 2 times and immediately sat down at the turret, after 30-120 seconds the trophy fell out

The trophy is not as difficult as it might seem at first glance, it is a bit random because there is no way to count the zombies. I advise you to play together, one player has an Apothikon Servant, upgraded to Estum Ot. How to upgrade this super gun, watch the video , another player has an upgraded Electric weapon. It's also better to slowly tug at the box for Ragnarok, Arnie. With this set you can stand quietly until round 70. We stood at the pyramid near the decomposition cannon. Take Gubl-Gammas for cartridges, sales, profitable exchanges, complete the test that gives bonus cartridges from the chest. We managed to make a trophy on waves 51 and 53. When there is already a sufficient round, ask your partner to make 1 circle at the pyramid, throw Arnie so that the zombies don’t hit you on the sides and fry everyone in front. With a little luck, the trophy will appear with a delay.
