I have a model so far:


The handle is a rectangle because it fits the Blockhead's hand. OK?
Anyways what it will do is shoot a purple outline of a hexagon on the ground/wall/roof. It will blink once to show it is set, and when someone walks into it besides you....
Vote on what it should do above.
It has a 1-shot (short) reload animation, where the ammo barrel on the back spins.
