Mike Weber from PlanetXbox has written us to let us know they have a new first look feature on Halo. There isn't anything particularly earth-shattering, but it is a nice compilation of what we know so far, and a look ahead to what Halo will be upon release. They have especially nice things to say about the AI and physics code:

The aliens themselves will redefine what is normally meant by AI in videogames. The Covenant hordes in Halo react to both light and sound, seek cover when needed, and keep together in groups for attack formations. Certain aliens will also, occasionally, detonate any kind of explosive devices they may be carrying when you defeat them; a last ditch effort to take you with him . The game's engine also sports body model reactions, which means if you plug a creature in the chest, the chest area will reel from the impact.
