A member from the gametrailers community managed to get some information by a member from the bnet website that explains some of the things that were shown during the screening of Halo 3 on August 21st in Seattle.

- So, it was Frankie (Franklez) and Luke (lukemz) playing the entire time.
- They showed us what the Campaign Scoring screen looked like.
- They played through part of Tsavo Highway:
- You start in a garage-type place, and are given verbal instructions on what to do (basically, get the hell out of the caves).
- You get in one of the Warthogs, and leave the garage, going through the caves
- When you exit the caves, you're in areas bordered by hills. There are Grunts and Brutes every now and then (keep in mind this was on Heroic).
- They showed the Fuel Rod, Plasma Cannon (removable), a Flare was thrown at them, Brute Chopper, Drones, new type of land-based turrets (he sniped a Grunt out of one).
- Also, the Phantom's turrets fire much faster. The Phantom also has a plasma cannon on each side (the Phantom is open-sided), with a Grunt controlling each one, I believe.
- Later, on the highway, you could see the Ark and storm in the background, with Banshees flying towards it.
- Luke threw a tripmine at Frankie, and Frankie walked onto it, before quitting Tsavo Highway.
