Master Chief created havoc for the Covenant in the first game, and now, and the Arbiter has a lot atoning to do. Master Chief returns in Halo 2, which features new vehicles, weapons, environments, and more. This time, you can interact with your environment, wield two weapons at the same time, board opponents’ vehicles, and even switch sides to play the role of a Covenant Elite. The Covenant alien race threatens to destroy all humankind, and the only thing standing in its way is a genetically enhanced super soldier.
