Tron was intended to be different than the typical Halo 1v1 map. It requires two primary areas of focus: movement and power item control. Failure to succeed at either one will be punishable by death. Keep one eye on your feet and the other on you timer.
Designed for 110 movement speed. There's a 1v1 gametype in my fileshare.
The Sniper, OS, and Speed boost are all on 60 second dynamic timers.
