Strange how sometimes the most fun you have with a game is in ways that weren't originally intended. The Bungie guys uploaded the Rocket Race VIP variant to Bungie.net - if you have Halo 3, grab an odd number of friends and try it out.
It's essentially two-man invincible teams with rocket launchers and mongooses trying to keep one another from reaching checkpoints. It is pure, unadulterated chaos and it's hella fun. Especially when two teams crash into each other and the VIPs beat each other up with the blunt end of their rocket launchers while their teammates flip their rides back upright.
I've gotta try this on Narrows next.
