For enhanced remake on Xbox 360, see Halo: Combat Evolved Anniversary. Bungie began development of what would eventually become Halo in 1997. Initially, the game was a real-time strategy game that morphed into a third-person shooter before becoming a first-person shooter. During development, Microsoft acquired the studio and turned the game into a launch title for its new video game console, the Xbox.
