The map, named "Powerhouse" offered a good showcase for the technical work they've done improving the game engine over past entries.
Every part of the Xbox 360 exclusive's world has received a several fold increase in detail. This particularly stood out in the weaponry.

Reach is a grittier take on Halo, creative director Marcus Lehto explained.

It will be interesting to see how the legions of fans respond to this new single-player approach.

And after being dethroned as the King of Live, I'm sure Bungie relishes the thought of retaking that crown this fall.
