Easiest way to do this achievement, is start a survival game on Dark Carnival Concert Finale. Pick up the ammo crate, and deploy it. Now have everyone pick up some of the ammo from the ammo crate.

I got this by deploying the ammo, of course, but did it on "easy" with 3 AI bots as my teammates. The bots picked up the ammo automatically. No need to go online multi-player.

This one is easy, when you see a yellow box like the one in the picture below take it and deploy it. Easy way is Single Player with bots they will take it automatically.

Pretty self explanatory. Throughout the campaigns you'll find ammo upgrade boxes (incendiary / explosive) which you can pick up and deploy while holding RT. To get this achievement all of your teammates must pick up the deployed ammo as well as yourself. Once all four teammates have collected it, achievement unlocked.

Note: You must have a primary weapon in order to collect the upgraded ammo. A shotgun, uzi, rifle, etc. Pistols don't count.
