Halo is a military science fiction media franchise, originally developed and created by Bungie and currently managed and developed by 343 Industries, part of Microsoft's Xbox Game Studios. The series launched in 2001 with the first-person shooter video game Halo: Combat Evolved and its tie-in novel, The Fall of Reach. The latest main game, Halo Infinite, was released in late 2021. Combat Evolved started life as a real-time strategy game for personal computers, turning into a first-person shooter exclusive to Microsoft's Xbox video game console after Bungie was acquired by the company. Bungie regained its independence in 2007, releasing additional Halo games through 2010 before moving on from the franchise. Microsoft established 343 Industries to oversee Halo going forward, producing games itself and in partnership with other studios.
