Thanks to UHYVE at Ascendant Justice for scouting this one down. Inside you see images and a link to two separate videos of Halo 3 gameplay. Granted, this footage is quite poor, but it's the closest you'll get to actually seeing the game in action for now. This version is the alpha currently being tested by 10,000 Microsoft employees and includes High Ground, Valhalla, and Snowbound. Here, a few of America's finest got to preview the game while they trade real bullets in Iraq.
