Microsoft has announced that Halo 4 will launch worldwide on November 6. A special segment tonight on Conan O’Brien on TBS will help promote the Fall launch of the title.

“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.”
