Alot like the others.
Single-player is great has a good storyline fun to use the weapons and equipment. It did seem a little on the short side, but it definetly kept me on the edge of my seat the whole way through. To easy on single-player i found myself beating the game on Legendary in about 8 hours.
Multiplayer was a huge dissapointment. It seemed to slow down alot, and even though people say its much more balanced I don't think so. Halo 2 was much more balanced and they made the pistol un-usable in Multi-player. I also miss the old maps I thought this would change with the new map pack coming out, but it didn't. The only time i play this game anymore is when my friends come over and we have a bunch of fun. If you want intense Multi-player check out Call of Duty 4: Modern Warfare if your more into the story check out Mass Effect.
