Combat Arms (and the PC version of Devil's Third). Shadow Company is slated for 2013, runs on Unreal Engine 3 and, like Combat Arms, is a free-to-play military shooter. It promises "highly intense multiplayer gameplay" including the "Blackmoney" mode, which has four teams of four players going at it. Honestly, it's hard to imagine Doobic topping the innovation of the "nut shot."
Nexon will also be showing an unannounced, free-to-play naval RTS game. Check out a gallery of Shadow Company shots below (which doesn't feature any shots below, if you get our drift).
