Master Chief returns in Halo 4, part of a new trilogy in the colossal Halo universe.
almost five years after the events of Halo 3, Halo 4 takes the series
in a new direction and sets the stage for an epic new sci-fi saga, in
which the Master Chief returns to confront his destiny and face an
ancient evil that threatens the fate of the entire universe. Halo 4 also
introduces a new multiplayer offering, called Halo Infinity
Multiplayer, that builds off of the Halo franchise's rich multiplayer
history. The hub of the Halo 4 multiplayer experience is the UNSC
Infinity – the largest starship in the UNSC fleet that serves as the
center of your Spartan career. Here you’ll build your custom Spartan-IV
supersoldier, and progress your multiplayer career across all Halo 4
competitive and cooperative game modes.
