Ubisoft and Best Buy announced today an online video game tournament for Tom Clancy's Ghost Recon Advanced Warfighter on the Xbox 360. The tournament will be facilitated by the Global Gaming League and kicks off on the Xbox Live online game service April 1 and continues through May 1. Entrants must have Xbox Live Gold to participate.

For the first three weeks of the competition, teams of two will compete against thousands of other teams as they eliminate each other for the top spot to compete in the deathmatch final. The two finalist teams will then travel to E3 and compete for the grand prize of an all-new 2007 Dodge Caliber, a sporty five-door compact car with a powerful stance that provides the functional flexibility of an SUV. The first- place winner will also receive $5,000 and the second-place winners will each receive cash prizes of $1,000.

Tournament registration began March 19 and ends March 31. For further information and to check the official rules, visit the registration site at this address.

The two teams that make it to the finals will battle for the grand prize of a Dodge Caliber at the 2006 Electronic Entertainment Expo (E3) at the Los Angeles Convention Center on May 11.
