Was sick of COD, but the inclusion of Kevin Spacey, and the fact that survival mode has been re-included enticed me enough to pick up the game. I have finished 3 chapters of the single player campaign and I am extremely disappointed. The 'new' engine they are supposedly using just seems like a highly modified version of the old engine. There is a total lack of physics, clipping (especially from the melee attack), blood, and I absolutely detest hit markers in the single player. Most of the set pieces are complete and utter chaos where you are being shot from every direction and it is extremely difficult to differentiate between allies and enemies.
