That said, the campaign's interactive cut-scenes can get tedious at times, there are times when its action sequences drag on, and its ending is a bit too heavy-handed. All of which is aided by this series' always intuitive controls. What hasn't changed - whether you play the campaign, multiplayer, or the co-op zombie mode - is that you still engage in a series of harrowing firefights that will test your reflexes and your trigger finger.
