So the bomb dude should give you finger mortar ammo (it should have gravity so not a rocket launcher instead a mortar because the player is already to OP) and the reg enemies give both rifle and revolver ammo because they are about the same minus damage and have a humanoid shotgunner (maybe not humanoid just a multi plasma thread shooting thing) for shotgun ammo
there should be a more distinct enemy pallet or don't make the maps black and purple because they blend in the background a bit (the red on purple also looks a bit harsh so maybe change the purple) new weapon idea: fork = melee and wet sock a throw able weapon that makes the floor lose traction for you and enemies (also I recommend redesigning the weapons to be unnecessary but cool looking like quake 3 and unreal tournament good example is unreal tournament's rocket launcher look at that for reference for how I think the guns should look and animate unnecessary
