Halo: The Master Chief Collection is a compilation of first-person shooter (FPS) video games in the Halo series for the Xbox One and Microsoft Windows. Originally released for Xbox One on November 11, 2014, and later in 2019 on PC via Steam, the collection was developed by 343 Industries in partnership with other studios and was published by Xbox Game Studios. The collection consists of Halo: Combat Evolved Anniversary, Halo 2: Anniversary, Halo 3, Halo 3: ODST, Halo 4, and Halo: Reach, which were originally released on earlier Xbox platforms. Each game in the Master Chief Collection received a graphical upgrade, with Halo 2 receiving a complete high-definition redesign of its audio and cutscenes that are exclusive to the collection. The game includes access to the live-action series Halo: Nightfall as well as the Halo 5: Guardians multiplayer beta that was available for a limited time.
