The latest screenshots for Bungie's Halo 3: ODST star grizzled series veteran Sgt. Johnson, who can be used as a playable character in the cooperative Firefight mode so long as you pre-order the Xbox 360 shooter from any "participating retailer."
Halo 3: ODST has the most "positive purchase interest" of any game due out in over a month, according to a recent Nielsen Company report noticed by Gamasutra.
Packing a new single-player campaign that follows the exploits of orbital drop shock troopers prior to the events of Halo 3, Halo 3: ODST is due out on September 22. Along with the new Firefight mode, the game also includes every Halo 3 multiplayer map released thus far, plus three new ones, and multiplayer beta access for Halo: Reach.
