While melee and regular weapons have a large pool of real world equivalents to take from, that's not the same for Energy weapons, which obviously require more imagination. So let's see if we can come up with something new and interesting. Already existing types of weapons: Plasma - pistol, rifle, caster, defender - Incinerator, flamethrower Electromagnetic wave: - laser pistol, rifle, gatling, - Gamma gun - Gauss rifle - auto-charging laser rifle and pistol - Solar Scorcher - Euclid C finder - holorifle Electric: - tesla beaton and rifle Sonic - Sonic weapons variants Bioweapon (?) - Syringer I think there could be space in the bio and sonic categories to develop more weapons. Chemical too, since they haven't been really explored. Gravity also hasn't been fiddled with.
