Starting on January 19, three training sessions will be held: Sniper School, Heavy Weapons, and Vehicles, with registration for Sniper School now open at the official site. Those who register their Xbox Live gamertags and then play an online Halo 3 match will also be entered into a sweepstakes to win a framed Master Chief print or 800 Microsoft Points.

Registration for the championship tournament itself will open in March, with the games to begin in April.
