(adsbygoogle = window.adsbygoogle || []).push({}); Me and a friend where playing split screen co-op and at a later round he died. When he respawned, he upgraded his pistol and got two pistols. Upgraded version and a normal version.

Basically, if you just have a pistol and you upgrade it, you will get an upgraded colt and a normal one.

BUT WAIT----
Im thinking this could be exploited. Say your in a situation. You have 2 guns, (eg. MP40, Thompson) You upgrade the thompson but was downed while you tried upgrading it. You where revived but you where unable to get the Thompson in time so all you have is an MP40.
What you could possibly do is Upgrade the MP40 that you have then you would recieve an Upgraded MP40 and a normal one.

Its just a glitch me and my friend found so dont flame if you dont find it useful. This is the glitch section after all haha ^

that could be really cool altough i dont no why u would need 2 rayguns, they would prob both use seperate ammo cuz they shoot different colours

2 guns of the same type DO NOT WORK trust me it will just replace the duplicate and give you one gun slot and then you are screwed with just a paped colt. DO NOT FOR THE LOVE OF GOD TRY THIS!!!

nice find ill try

I tried up grading the "free" colt. well, at least a kid I was playing with did. anyway, he said he couldnt do it. it just wouldlt let him!

NO, this is no trick or whatever. When you start zombies you actually have 2 guns, 2 pistals. But since there the same guns you can switch from gun to gun.. SO when you updgraded one you stil had the other.. thats also why sometimes when you have the wunder waffle and see it in the box again and pick it up, youll only have 1 gun.. its hard to explain but most people dont get it..
