Halo: The Master Chief Collection consists of every title that Master Chief has ever been in; Halo: Combat Evolved Anniversary Edition, Halo 2, Halo 3, and Halo 4. If you are looking to play the shitacular awesome Halo 3: ODST and perhaps what is the more better attempt at telling a story without Master Chief; Halo: Reach, then you need to fire up your Xbox 360. Each of the titles received some sort of graphical upgrade with the most attention going to Halo 2 due to the release of Halo: The Master Chief Collection being the 10 year anniversary of Halo 2. Never before seen cutscenes were added
