Halo: The Master Chief Collection

Halo: The Master Chief Collection is a compilation of first-person shooter video games co-developed by 343 Industries in partnership with Certain Affinity and Saber Interactive, and published by Xbox Game Studios. The collection includes the first six main installments in the Halo franchise released between 2001 and 2012, originally developed by Bungie and 343 Industries. It originally released for Xbox One on November 11, 2014.

At launch, the collection comprised the first four main entries in the franchise: Halo: Combat Evolved Anniversary (2011), Halo 2 (2004), Halo 3 (2007), and Halo 4 (2012). Each game received numerous graphical and performance enhancements, including increases to resolution and framerate, while Halo 2 was fully remastered as Halo 2 Anniversary, receiving a full redesign of its art, audio and new cinematic cutscenes produced by Blur Studio to commemorate the game's tenth anniversary. The single-player campaign component of Halo 3: ODST (2009) would be added to the collection in May 2015. The collection would be procedurally released for Windows between December 2019 and November 2020, coinciding with the additions of Halo: Reach (2010) and the Firefight multiplayer for Halo 3: ODST. The game on Xbox One includes access to the live-action series Halo: Nightfall, and hosted the Halo 5: Guardians multiplayer beta on Xbox One that ran in 2014–15.
