The Master Chief Collection consists of Halo: Combat Evolved Anniversary, the anniversary edition of Halo 2, Halo 3, and Halo 4, complete with their full catalog of extras, including all multiplayer maps and gameplay modes. There have been no story or gameplay changes to the original releases.The games are first-person shooters with vehicular combat that takes place from a third-person perspective. All four campaign modes can be played alone or cooperatively via split screen or Xbox Live. Each campaign has four difficulty levels and access to gameplay modifiers known as “Skulls”. As in Combat Evolved Anniversary, Halo 2 players can swap between the original and upgraded graphics on the fly. Additions to Halo 2’s campaign mode include “Terminals”, and new prologue and epilogue cutscenes to link the series for Halo 5’s debut.Since only six of the game’s multiplayer maps were remastered, there are two Halo 2 multiplayer modes. The Halo 2 anniversary multiplayer mode uses the six remastered maps, while the standard Halo 2 multiplayer mode includes all of the original game’s released maps with a full graphical update but no remastering.The Collection multiplayer includes Mission Setlists, curated lists of levels selected from throughout the series.
