Scottish, you can't fire a missile at a creeper who is 10 feet away from you and missiles are a pain in the ass to build. Plus, the enderdragon doesn't collide with missiles. I think an easy way to add guns would be to just add a handgun, a sniper, an smg, an assualt rifle and and a shotgun, and then a bullet is crafted with an iron and a flint on top of it gives you ten bullets and if you craft a battery onto a gun it shoots electricity and becomes more powerful and I get off topic but maybe also add a laser sight to make it at least somewhat use UE.
A flashlight or flashlight helmet would be handy, too.
