"Halo 4," the hotly anticipated sequel to the popular franchise, will launch worldwide on Nov. 6, 2012 exclusively on Xbox 360.

"Halo 3," the biggest consumer product launch of all time when it released in 2007, concluded the original game trilogy, but left many unanswered questions around the fates of the series' hero, the Master Chief, and his artificial intelligence companion, Cortana.

"Halo 4" marks the return of legendary hero Master Chief, named by Fast Company as "one of the most popular characters in gaming history". Master Chief returns to confront his destiny and face an ancient evil that threatens the fate of the entire universe.
