My idea is a stun baton but deadlier and meant to kill not to capture, but alas it makes no sense as successfully stunning an alien who has been captured before is the same as killing them, thus the weapon is for show not for actual application. Might i add that the appearance would look good as a beam sword (Much like a lightsaber). I'm not sure if this can be actually done as i'm not that experienced with mods in this game, although from what i hear only aircrafts, guns, shields, and vehicles (and a few more) are stuff that can be changed. At the very least it's an alright noob concept.
