If you are going to vote down, please comment as to why. I don't feel the existence of other solutions that are easier due to utilising glitches warrant a downvote, as in a game like CoD these will almost certainly be patched in due time. EDIT: They have been patched-did someone pick up the phone? Cause I called it.

Right, I have now done this twice, once in which I got the achievement and once in which my mate got it but I got both weapons to 20 again as well (please find the tail end of this run in the video below and use it with this wall of text to your benefit). This is the hardest achievement on the DLC, much harder than the Easter Egg IMO and requires a great deal of player skill and luck. Lets get down to brass tacks.



First I'm confirming that this has to be 2 weapons on your person, in the same game. Lets dispel any theories on getting this across multiple games now, I have had a level 20 Cauterizer twice (once when playing solo where I also had a level 16 Ameli-arghhhhh) and in the game when I got the achievement it only popped when I upgraded my second weapon to level 20 (the first was a Pyatek, second was S12, I actually used these two guns both times I have done it, my mate used Pyatek and Ameli). We did this with just 2 players but it may be easier with more and I'd actually gotten pretty close to doing it solo 3 or 4 times. This guide is based on you having at least 2 people, to do it solo using this method would probably be impossible, you'll just have to be very skilled at playing zombies and train them around the starting area if you really are intent on soloing it.

Right so each upgrade costs 2500, that means each player who is going for the achievement needs 95K just for weapon upgrades alone. That's not including perks, weapons and the doors (as in the actual physical doors you have to open, not the 1960's Los Angelean Rock Band "The Doors"-just to avoid any confusion). As such you can't afford to spend more than about 5K each on the box I would say. As a team you need 4,250 points to open all the doors you need to I believe.

You need to have an LMG, I prefer the Pyatek (I don't know for sure but I think it packs more of a punch than the Ameli and also has 25 extra rounds in the box magazine-doesn't sound like much but when you have a line of 20+ zombies running down a corridor or in a train towards you 25 rounds could well be several thousand points or the difference between life and death. The Ameli, being essentially a modernised 5.56mm Spanish copy of the MG42, is a true burp gun, it's rate of fire seems a lot faster than the Pyatek's so you will be reloading it a lot more often and it also has more recoil), but if you get the Ameli, keep it. Secondary weapons should be either the Cauterizer, S12 (really underrated little gun, I think it outperforms the Cauterizer in everything but overall ammunition-a real room-clearer), ASM1 or HBRA3 (don't bother with any other SMGs or Assault Rifles-the ASM1 is nice and accurate with a lot of stopping power even on higher rounds and the HBRA3 is the same but both will run dry pretty quickly hence why they are your secondaries. With the exception of the HBRA3 don't bother with wall guns-they are complete shite).
Only perks you should bother with are Exo Health which is a must and Exo Reload which is your decision. If at least one of you can get Distraction Drones, that is a real bonus (the benefits of the Distraction Drone should be obvious to anyone who has played this mode), less so Nano Swarms but they are still useful (throw them on a downed teammate as you revive them or into a chokepoint as a lot of zombies rush you).

When you start, point whore on zombies by shooting them a few times in the legs and then knifing them to maximise points. You also get 100 points for turning on any power source so do that to the one at the start. Now this is really important, when you have enough points, open the LEFT door, do not touch the one on the right at all. Once in, point whore a bit more and open the door to the Morgue. You may all want to get at least one go on the 3D printer here to get a half-decent weapon and then you want to open the doors to Administration (the one from inside the Morgue-not the outside door remember), Holding (so you can get Exo Health) and the Exo Room (via the Morgue). Once these are all open, maybe invest points in a few more goes on the box unless you already have some decent weapons and then that's it. Once you have started upgrading weapons, do not even concern yourself with the box, it's unlikely you will get the exact weapons you want and wasting too much money on it is counter-productive to the aim.

Now, you know where the decontamination area is? That's our Alamo, our Rorke's Drift, our Gandamak, our...you get the picture. You can't be flanked from the right because we kept that door shut and we've all seen the film 300 right? Where 300 Spartans (although in real life there were also 3,000 other Greeks at Thermopylae too) hold a narrow point from a force of Persians many times larger? That's what we are doing here, bottle-necking them so that their superior numbers count for nothing, only instead of Aspis and Dory we are using Exoskeletons and Light Machine Guns. There's also a weapon upgrade station in this room with you-talk about all-inclusive, Thomas Cook doesn't do holiday deals like this place.

From here, just survive. I would suggest using your LMGs first as they create more points and then switch to your secondary if you must reload and don't have time when the living dead are bearing down on you. Be sure to keep one or two zombies or better yet crawlers at the end of the waves so you can all sort your lives out and go and buy whatever perks you may need or pick up the orbital drops. Save your Distraction Drones for when your mate gets knocked down or you are really being swamped (remember that you get a free one back each round so don't be afraid to use them). Zombie Camo also comes in really useful in these instances although you may want to clear the zombies out while they ignore you otherwise your pal will likely be swamped as soon as you revive him.

Do not open that door on the right unless you are adamant that it is your only way of survival, once that door is open this method is compromised and you must rely instead on your own skill, luck and maneuverability. Having said that, surviving is obviously imperative and you must do whatever it takes to do so. It really is the only chokepoint like that on the map (we tried the room at the bottom of the staircase between holding and the exo room with the door on the left as you face the stairs still shut but it's hopeless for holding out and just good for buying time if you lead all the zombies round that way and then open the door). We actually jumped ship a little earlier than i'd have liked on the time I did it (about Round 18) and from there just had to survive in the starting area (which is a lot more skill based than the tactical approach of staying in decontamination), which I wouldn't recommend, and on subsequent attempts the two of us have survived up to Round 27 just in that room before we got downed after being backed up to the wall by zombies and trying to fight through to the doorway and escape (new PB in that room is 31-as you can see in the vid).

A few quick tips, some of these might seem obvious but a lot of people don't seem to adhere to them.

Communicate with each other. Ammo saves lives, don't go picking up the Max Ammo until you are both fully loaded, a Magazine can make all the difference. What's more if you are putting a Swarm Grenade or Distraction Drone down, let your oppo know so he isn't wasting one too-it's likely if the shit is hitting the fan for you, it is for him too.

Make the most of the Hyper Damages. You get more points for a melee kill so don't just go shooting everything you see, if you can melee an enemy to death without getting ripped apart in the process, then do it. Maximise your points.

Exo boosting. I reckon i'm pretty good at zombies. The exo suit makes me immense at zombies. Double jumping and exo strafing really is a life saver and can get you out of a sticky situation 9 times out of 10. Just watch out for those pesky EMP zombies, make sure you are prioritising them.

Grenades are actually pretty powerful even in later waves on this one. Don't neglect them. It may actually be an idea to upgrade them to contact grenades (the slot is in the corridor next to Exo Health but i've never thought to do this before now).

That's all i've got for now but if I think of anything else, i'll be sure to add it. If you are going to vote down, please tell me why so I can strive to improve the guide and help you guys out more.

Good luck.

Cheers.
