I feel this game is fun, but after the easy 4 hour campaign, and the 6 or so hours online, I am done with it and I am glad I only rented it. Most frustrating part for me were the useless friendly AI on the campaign. The multiplayer ... I am sorry...is garbage. Most frustrating part of Multiplayer was the several times I unloaded 20 plus bullets into someones skull, and they managed to kill me, and the game tells me they have 80 percent of life left. If this was 5 years ago, I might have enjoyed it a lot more. But the bar has been raised a lot, and I do not have time to play half baked games. Sending it back and hopeing Master Chief knows how to kill someone when you shoot them in the head.
I gave it a 7 out of 10 because the story line was decent, still the most realistic looking game since the last one. Campaign was only about 3-4 hours of game play on "normal" but yet again the online component was lacking.
