Halo 2. We don't really need to say anything more than, "When can we all get our mitts on this game?" It's an amazing-looking trailer, so keep in mind that what you are seeing is actually in-engine--not CGI. The show starts off with the original Halo movie from E3 2000 that left showgoers stunned. Also look out for the WartHog Jump video, directed by Randall Glass, in which he uses the physics engine to demonstrate the heights a WartHog will go when properly motivated.
