AWESOME!! BUT PLEASE UPDATE!!

im not gonna lie, i like gun building 2 batter than 3. But please update this one so it has the fetures of gun building 3 such as shooting the underbarrel grenade launchers, customizing the reticles and magnifications of scopes, melee, weapon swaping, and a better zombie game. I paid for this app and not for 3 so please update this please!
