In a surprising move, Microsoft have confirmed that their hithero mostly-X-Box-exclusive Halo video game series is coming to PC.
The original Halo: Combat Evolved (2001) had a well-received PC port, but Halo 2 (2004)'s PC port was poor and badly reviewed. Subsequent games were not released on PC at all.
The Halo: Master Chief Collection is now coming to PC. This will include revamped and upgraded versions of Halo: Combat Evolved and Halo 2, but, for the first time, Halo 3 (2007), Halo 3: ODST (2009), Halo: Reach (2010) and Halo 4 (2012). The spin-off Halo Wars strategy series and Halo 5: Guardians (2015), the most recent game in the main series, are not included.
Microsoft plan to release the games this year, although they will be releasing each title individually so they can test and optimise each game through a releasing and testing period. Microsoft will be releasing the game via their own online store but, surprisingly, also through Steam.
