I dono what it is but I just don't care much for it. At first I thought it was pretty fun but still not as good as COD4 (owned that for PS3), but the more I play it the less I care for it. I think the no dedi servers thing contributes..makes it feel less fun no doubt. A perk for a PC game should always be dedicated servers..I don't know.
