The Idea
A disposable, one-shot zip gun. A emergency weapon you only get one shot for. High damage( 60-90 damage or so. Finishes off wounded targets) to the head, low damage(10-25 damage) to anywhere else.
The purpose of this?
Jail RPs and Deathmatches, maybe. Shoot a guard with a zip gun, and finish him off with your fists? Find a injured guard and finish him off with a zipgun? Punch a guard a few times and shoot him? Run out of ammo in a deathmatch and pop off one last shot before dying?
Maybe make it a default gun, but smaller? (Maybe if its just resizing a default gun, people would actually give a stuff about suggestions and requests, as opposed to actually modelling something just because a random stranger wants it with no reward other than feeling good for 5 seconds.)
