hmm... this doesn't have much to do with the idea itself, but personally, I feel like this weapon would make more sense if it was added after or with another ranged weapon so that the balance of melee to ranged weapons isn't off, but that's just me :P
well, I think that this weapon would be both ranged and melee, so if there's 2 melee, 2 ranged, and 1 both, the game would be balanced-this would also allow for new enemies, because apparently literally every weapon (and the jetpack) has to have it's OWN enemy type :3
