oh yeah. it just occurred to me that the pipegun should probably be excluded from firing 40mm grenades, because then it would basically be better than the riot launcher?

oh, and notes on the airgun.

consider letting it fire stuff that continues going offscreen, because otherwise it doesnt offer a lot of improved functionality over a throw, does it?

stuff shot by the airgun should do enhanced damage on impact depending on the pressure it is shot with, possibly embed into ppl or cause bleeds if its something like a rod, shard, arrow, etc.
