Ok I just unlocked the Gauss attachment for my SCAR in MP. Figured I'd see what it does. So I enter a few games to try it out only to find it seems to do nothing...? I looked at the challenge for the attachment which says get so many kills with it, so I pressume it damages the enemy. Yet I fired 3 shots at a guy point blank, no chance to miss and it just didn't seem to do a thing to them.
What exactly is it meant to do? Is it broken?
