Halo 4's episodic co-op campaign Spartan Ops will go on hiatus next week, concluding in January with the final five episodes of season one. Microsoft is also teaming up with Virgin gaming on the "Halo 4 Infinity Challenge," which has a V8-powered 2013 Ford F-150 SVT Raptor (pictured), along with an appearance in a future Halo game, as its grand prize.

Those interested in participating in the Mountain Dew and Doritos presents, in association with Seven Eleven and Harvey's RV World, Halo 4 Infinity Challenge can registers at www.halo4infinitychallenge.com. The tournament begins December 17 and will track War Games and Spartan Ops leaderboards, with over 2,800 prizes available. The qualifier phase will run until January 10.

After the qualifier section, players will be tiered into three groups, with the final phase taking place the week of January 12. Leaderboards will be reset at this time to award the top performers in each tier. No word yet if the new Ford F-150 handles like a Warthog.
