many of the weapons in this game have bipods modeled onto the gun, but they currently serve no purpose. At first I thought bipods were simulated when you went prone, but then found that the scope on a sniper still went all wobbly when you run out of breath, which wouldn't happen with a bipod, which essentially removes wobble and removes muzzle climb.
We should be able to deploy the bipod, which takes maybe a second, or simply run around with the bipod activated. Having the bipod as a removable attachment would be nice too.
