-Lackluster storyline, which led to a boring campaign
-I pity the fool who has this game, and no XBL
I first got this game along with a 12-month subscription to Xbox Live, and I was fortunate for that. I played the whole campaign first, and was disappointed that it was boring and short. Then, I went on XBL, and everything was different. The multiplayer is mainly better in general because instead of playing dumb AIs that don't even care about dying, to real people that think and act just like you. That changes everything, and suddenly, the game is competitive and exciting.
