PJZ: Single shot Grenade launcher

A new project Zombie weapon!
This time its a single shot grenade launcher. Its and over and under (that what you call it right?) action grenade launcher. This means that you load it by putting the barrel up, remove the old round and put a new one in.

For the guys or girls that don't know what project zombie is let me explain. Project Zombie is a game that I'm developing. You guys also can make weapon for in the game by uploading weapons to this group.
