Gears of War 3 - We're getting 4 player co-op gameplay here. New gamplay elements straight off. Can charge at enemies with a new rifle weapon and deal a killing blow. Some enemies look to need amputating, the mutations mainly. Berserkers back, Lament versions. From what was shown, there was a bit of 2 female cogs, Cole and Marcus. So it looks like there is more than 4 characters you will play as throughout the game. Will be unveiling a new mode called "Beast" later on.
