I posted this discussion because I ran out of ideas to add into my game.
also, if your suggestion is really good, i will add it in my game, and give your best game a like on facebook. just send me the link to your game.

For guns: Grenade launcher, shoots wide-range grenades
Shotgun, shoots three different ways
Minigun, big bullets and very fast shooting.
Ray gun, constantly shoots lasers
These are some obvious ideas I could think up :slight_smile:
