Halo 2

Halo 2 is a first-person shooter developed by Bungie and the sequel to Halo: Combat Evolved. In the campaign, you switch back and forth between two playable characters: the human super soldier Master Chief and the Covenant warrior known as the “Arbiter.” The game introduced online multiplayer via Xbox Live, featuring an automatic matchmaking system, the dual use of certain weapons, and the ability to hijack vehicles. It supports both cooperative campaign mode and competitive multiplayer mode and was the best-selling game on the original Xbox.
