Idea

This idea popped into my head. Im not totally sure your going to like it, but how about having single-shot weapons (like shotgun and sniper) knock you back slightly when you fire?

Wouldn't it get annoying after awhile? I mean, imagine being on a ledge, firing a sniper rifle, then flying back into the lava because of the little force that tipped you over.

Besides, it's just not reasonable. Do you fly back when you fire a shotgun? It would have to have six barrels to actually move your whole body noticeably backwards. The ET shotgun seems to have half of one barrel.

Every reaction has an equal and opposite reaction.
Shotgun knocks back when it hits. I win. :P
Maybe not doing it with the sniper, but it would be awesome on the shotty.

Double Barrel shotgun if ever applied I would agree for a knockback, but that idea isn't too great, I don't find it fun.
A sniper is ment to go far, in REALlife it won't push you over an edge (Once you fire a gun, you'll know how far back it goes and you can equel that force in strength)

if this guy can hold 2 heavy machine guns and fire at once and not fall from recoil, why can't these people with just a single rifle? this suggestion can also be countered by, these are trained people or something like that
P.S. i have 1 more post than u crystal >.> until u post below me or somewhere

Awkward.. I'll have two more soon.

Yeah, Knockback will only apply to dwarves, they fly.
