That being said, I am slightly disappointed with the co-op. If you are using a widescreen TV, BE WARNED, co-op mode will put black bars on either side of the screen. Not only are you losing 25% of the screen real estate that you paid high dollar for, you also risk suffering BURN depending on your TV and game play habits. Bungie could have at least incorporated some moving pixels or something to prevent it, but no.
Other than that, the game looks great (not perfect but great) and the new weapons and items add a different spin and change some strategy.
I love you bungie, and I wanted to give you a perfect 10, but I can't in good conscience.
Best 360 game out right now. The graphics are way better than HALO 2. I bought the limited edition of HALO 3 and the limited HALO controllers. A recommendation, play it on normal, my friend played it on easy and hes already on the third level out of 9. This is game you should definitely add to your 360 collection.
