343 Industries have just announced the Halo 4 Infinity Challenge. An international free-to-join tournament that will take place during the Spartan Ops mid-season break.

The tournament is broken up into two parts. A War Games based tournament and a Spartan Ops based tournament. The War Games tournament will basically be a global leaderboard that tracks the number of kills and points you earn. Whereas the Spartan Ops leaderboard will track the number of chapters you complete.

This is yet another great way 343 Industries engages it's community. The participants have a chance to win from over 2,800 prizes including the Ford F-150 SVT Raptor truck as the 1st place prize in the War Games ladder and the winners of the Spartan Ops ladders will have a chance to be featured in the next Halo game. Pretty sweet, you can sign up here.
343 Industries will also be releasing a patch before the launch of the tournament and we'll be keeping a keen eye on all of the participants for cheats and various exploits. The tournament coincides with the release of the Crimson Map Pack. Don't forget to check out all the achievements that will be coming with the DLC.
