"I hate the shields. I hate them. IF THE GAME HAD MODES "RANKED" MODES WITHOUT SHEILDS I WOULD BE THE NUMBER ONE PLAYER IN THE WORLD. I HATE THE SHIELDS. IT MAKES NO SENSE." I hate to be the one to answer, but it's called tactics. Maybe stick to Gears of War?

Huge difference.... there's a lot more depth, shading, massiveness, better textures etc etc.
