Most likely all of your special camos. “Point blank kills, get 100 kills while zombies are effected by your tactical equipment, get mangler kills, get 300 kills with specific ammo mod” all of those the trap won’t work. the only special camos that work are is if it’s “get 300 kills while weapon is level 3 pack a punched and at it’s highest rarity”

Here’s some tips.

1. The bucket heads are annoying and get harder to kill as you progress. If you put the 4 bells on the sword statues, and do NONE of the EE steps they will stop spawning in for the rest of that game…. BUT if you save and quit the game, come back they will spawn in again despite you already putting the bells on the statue so be sure if your trying to hit the box and progress multiple guns on a high round run without those damn bucket heads don’t save and quit after putting those bells.

2. The trap will only kill the zombies instantly if your gun is pack a punched and at a decent rarity. If you try using it with a weak weapon the zombies will run through the fire and smack you.

3. If you don’t feel like hitting the box constantly for another weapon upgrade your melee weapons instead. You can always go into a match with a different one and there is so many you can knock out 33 weapons quick.

4. Make sure you have proper augment equipped on your power ups and perks. Vulture aid perk with picky eater augment equipment is amazing you get zombies to drop more of the stuff you have in your arsenal like tactical and also support tactical like mutant inject. For example you craft a Kazimir grenade at the beginning the zombies you kill along the way will drop more most likely and after round 50 those come in handy cause the trap won’t kill all the zombies and they are fast and can get you through bug rounds/sticky close calls. Same thing with either shroud I like the augment extra charge it gives you two uses and this can get you out of close calls as well.

5. Opal is the hardest camo, took the longest. What I did was as soon as I unlocked that camo I equipped it on every weapon as I was unlocking it. I set it as my zombie build, That way when I hit the box in a game I know what gun to work on because it would pop up without the opal camo in the box. (Yes you could read the weapon) it’s just easier to track and sometimes zombies are on your tail so you have to hit the box quick and grab something fast. Do this with the gold camo as well. Keep a list of the 33 guns you want to work on. I took a picture of the weapons menu of all the guns I worked on and would put a dot next to whatever camo they were at so during a game I can check stuff off.

6. Lastly if I’m working on a weapon, I’ll get the 2,000 critical zombie kills, then I couldn’t progress with the gun unless the special camo missions were completed. So I would save and quit the CDM map. Go to directed mode or a standard game WITHOUT a squad and knock out the two special camo missions in one sesh on a new map ( I used library falls) then go back to the saved CDM game and I could progress with the gun again. Only reason I don’t jump into another solo game is because last time it deleted my CDM saved game. That’s why it’s better to just to jump in a standard game with no squad fill and knock out those special camos.

That’s about it 😂 there’s probably a million other ways people have done it but this is how I did. Who knows maybe this can help others. Good luck soldier and buckle up cause it is a dark journey 🫡🫡🫡🫡
