Halo 4 will launch worldwide on 6th November 2012.
The events of Halo 4 take place four years after the events in Halo 3. The game sees the return of Master Chief who confronts his destiny and faces an ancient evil that threatens the fate of the entire universe.
"We are beginning a new saga with Halo 4 and embarking on a journey that will encompass the next decade of Halo games and experiences," said Phil Spencer, corporate vice president of Microsoft Studios. "Millions of fans worldwide have been eagerly awaiting the opportunity to step back into the boots of Master Chief, and with Halo 4 leading the charge, we're confident 2012 will be the most successful year in Xbox history."
Halo 3 has concluded the original game trilogy in 2007, but left many unanswered questions around the fates of the series' famous hero, the Master Chief, and his artificial intelligence companion, Cortana.
