(adsbygoogle = window.adsbygoogle || []).push({}); To get this trophy you must buy EVERY weapon off the walls in one single match, me and 2 mates did it yesterday.

I suggest you play with 3/4 people as it is a very hard challenge

1st room:
Money needed for weapons: 1000
Money needed for doors: 1500

Buy olympia first with your starting 500 points as it is easy to get a bunch of 3-5 zombies in 1/2 shots with this on rounds 1-3, after everyone has bought the M14 and the olympia choose who will open the door taking you to the room before the alley.

Room before alley:
Money needed for weapons: 1000
Money needed for doors: 1000 (I think)

Right you now have access to this room and the starting room, try and knife zombies until you have to bring out the M14 and spray like hell. Once you all have enough to buy the MPL in this room the second person will have to open the door.
Tip: swap the olympia for the MPL as round about now it will be an awful gun


Alley:
Money needed for weapons: 1200
Money needed for doors: 0

Buy the ak74u and try get out of here asap. Once you all have bought it player 3 will open the second door in the first room.
Tip: swap the M14 for the ak74u as it is a fully auto gun and the M14 will only do you some good when you are on very low rounds.

Room upstairs from starting point:
Money needed for weapons: 1000
Money needed for doors: 1000

Buy the pm 63 and then player 4 will open the next door.
Tip: swap the MPL for this gun as ak74u will be very helpful in higher rounds.

Speed cola room:
Money needed for weapons: 2500
Money needed for doors: 1250

In this room is the stakeout (1500) and MP40 (1000) buy the stakeout first and fight of zombies with the ak74u and then swap the stakeout for MP40, having the fully auto SMG will help lots.

Room before theater:
Money needed for weapons: 1000
Money needed for doors: 1250

Buy the MP5K and then just get to the theater as quick as you can!
Tip: swap the MP40 for the MP5K AK74u is still going to be good.

Theater:
Money needed for weapons: 5200
Money needed for doors: 0

In the theater you need to buy I would say claymore first as it can help so much, then the M16. Swap the MP5K for the M16 as they are both quite bad round about now.
Guess you think you bought everything? Wrong, now you need to buy the bowie knife. after you have bought it link the teleport and you need to get up there ASAP because all you need now is to buy hand grenades, if you there thinking "why won't it let me buy them?!" throw one out the window and after you have the collector trophy should appear in the corner of the screen.

Tips: If you have someone on your friends list who has done this get them to help, we had a mate who dint want it and he got the ray gun from the box it helped so much.

Does it work on solo zombies because I end up with around 30000 about round 30 odd?

It does not specify it has to be with anyone so I say go for it if you think you can do it.

The specification for it just says "Buy every weapon off the wall in a single match of zombies"

I recommend using this strategy though aside from the extra players as this way you get the ak74u early and it will make life so much easier.

im bout to do this anyone wanna help?

It does work on solo thats how I got it

I found it easier just to play normally and then raise your points to around 16000 and then buy everything.

By round 18 (max) you can do that trophy, and yes, it works on solo.

i did this its rlly easy just play with friends let them open the doors while u buy guns then if they wanna do it after you buy the doors and they buy guns

also i think kane forgot you also need to buy the grenades in the pack a punch room 250 points
