Microsoft and 343 Industries announced this morning that Halo 4 will launch worldwide on Tuesday, November 6. The news comes one day after teasy tweets from Microsoft's Major Nelson indicated some form of collaboration between Microsoft and everyone's favorite freakishly tall late night host, Conan O'Brien, which sparked rumors of a potential launch date reveal.

Microsoft studios corporate VP Phil Spencer offered lofty goals alongside the launch date announce. "With Halo 4 leading the charge, we're confident 2012 will be the most successful year in Xbox history," Spencer said. He also pointed out that Halo 4 is just the beginning of Microsoft's renewed relationship with the Chief. "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." Just no more cat helmets, Phil. That's all we ask.

Additionally, Halo 4 will appear in some form on tonight's episode of "Conan," which Microsoft described as nothing more than a "special segment."
