Halo: Combat Evolved for Xbox

I've owned an XBOX and Halo for around 6 months and I am simply amazed. The in depth gameplay, graphics, sound, and realism all add up to produce the best game ever made. Cheers to the developers, Bungie, for a job VERY well done. I've beaten Halo on Easy Normal and Heroic. Ok, down to the facts.
Halo has 10 levels, each increasing in difficulty with the first serving as a training level. It also has four difficulties for a total of 40 different scenarios on levels. And the levels are so enourmous...they're just plain huge. The point is, GET THIS GAME ASAP. You wont regret it the least bit.
