Remote Charges?
To me it looks like it fires remotely detonated charges (reminiscent of the weapon in Goldeneye: Rogue Agent, for those of you who know). That's just my take on what I saw. It would also kind of fit into the gameplay balance if there were such a weapon. It doesn't seem like an ordinary grenade launcher.--File:PENGUIN4.gifFluffyEmoPenguin(ice quack!) 14:52, 7 June 2011 (EDT)
