This is one of the greatest games that were ever made. The game is entertaining and very fun to play, especially with a friend/s. If you own an Xbox gaming system and you haven't played this game then you are missing our on one of the best action games of all time. The gameplay is excellent; it is almost perfect. The co-op option makes the gameplay better then ever. The AL is smart and fun to kill. I love throwing a plasma grenade on a grunt and watch him run around, then explode, and his body ending up on the other side of the room. The storyline is classic, original, and superb, with a big twist in the end. It keeps you hooked through out the game. The game's sound and music are very good. The sounds of the covenant could not have been any better. The graphics are great; maybe if it were realist graphics this game would be the best game without a doubt. The game also offers an excellent replay value. The system link option is awesome. Sixteen people fighting on teams of eight on eight is very fun. I absolutely loved play this game. No gamer should be without this game. You will not be disappointed when you get this game, and I highly recommend that you get this game. If you don't have an Xbox check out the PC version. I can't wait for Halo 2, which I expect to be better. Good job Bungie!
