Nearly 13 years have passed since Halo 3 debuted on Xbox 360, meaning a desire to see the game ported to PC grew alongside an entire generation of gamers.
Microsoft finally granted that wish, in accordance with its 2019 announcement. Therefore, you can now play Halo 3 unencumbered by any technical limitations, with the game being available for purchase not just on the Microsoft Store, but also via Steam.
Halo 3: ODST and Halo 4 ports also on the way
Following this release, Halo 3: ODST and Halo 4 are the only remaining games from the Master Chief Collection that are yet to see the light of RGB-heavy day on PC. Both ports have already been confirmed, however.
Halo: Infinite is also scheduled to launch on PC in the fourth quarter of the year, so the only installment from the long-running FPS franchise that still lacks a confirmed Windows port is the 2015 Halo 5: Guardians.
