Now you can play Halo: Combat Evolved AnniversaryHalo 3Halo: ODST, and Halo 4 on the Xbox One. Those titles from Xbox’s most popular franchise have been added to the backward compatibility library, joining Halo Wars from 2009 and Halo: Reach from 2010. The additions make every game in the Halo franchise playable on Microsoft’s latest console.

Aside from letting you play any of the games on the Xbox One, Microsoft is giving everyone the downloadable content for free. So every map pack, regardless if you bought it years ago or not, is yours.

Prior to this, Microsoft released Halo: The Master Chief Collection in 2014. It included remastered versions of each title; however, the playlists for multiplayer weren’t directly copied. People who got The Master Chief Collection for its story were fine, but online players saw different games mixed into playlists. If you wanted to play a specific playlist from only one game, you were out of luck until now.

The only title missing from the backwards compatibility library is Halo 2, which was never actually released for the Xbox 360. It was released for the original Xbox in 2004. You can still play it if you own The Master Chief Collection as Halo 2 was redesigned from the ground up for the Xbox One X.

Halo games made exclusively for the Xbox One include Halo 5 and Halo Wars 2. At E3 2018, Microsoft should be expected to unveil the next chapter in Master Chief’s journey.
