I bought an Xbox 360 just to play Halo 3. My brother and I naively thought we could play campaign and locally and we wouldn't really need to play online, so we didn't buy a big hard drive for it. Needless to say, that didn't last long at all. But one day we were playing 1 vs 1 on Sandtrap and he was wanting to drive the warthog. I had killed him several times and he was angry that I wouldn't let him drive around. He turned his warthog towards me and barreled down a stretch of desert right towards me. At the last moment, I threw out a trip mine and he hit it with his right front tire. The warthog went into a barrel roll in the air just high enough to avoid hitting me. As the cockpit of the warthog came into view, it was directly above me. I pulled out my shotgun and blasted upward into the vehicle and it was a direct hit. My brother's character died and the warthog came crashing to a stop behind me. It was the coolest Halo 3 moment ever. It was just like a scene out of a movie. We were so disappointed that we didn't have the hard drive to go back and film it on, that we went out and bought one so that we would never miss the chance to film some Halo awesomeness.
