Halo 2

The Covenant Alliance threatens to annihilate all of humanity, and the only defense against it is the Major, a genetically modified super-soldier.

The Major returns in Halo 2, which features new vehicles, weapons, environments, and much more.

This time, you can interact with your environment, wield two weapons simultaneously, board enemy vehicles, and even switch sides to play as an elite member of the Covenant Alliance.

Halo 2 also supports online multiplayer via Xbox Live.
