Halo 2 is a science fiction first-person shooter developed by Bungie Studios. Released for the Xbox game console on November 9, 2004, the game is the sequel to the blockbuster Halo: Combat Evolved. Since its initial release, Halo 2 has been the most popular video game on Xbox Live, holding that rank until the release of Gears of War for the Xbox 360 nearly two years later.
The game features a newly built engine, the Havok physics engine, new weapons and vehicles, new multi-player maps, and a continuation of the storyline from Halo: Combat Evolved. In the game, humans, who have developed faster-than-light travel and colonized several worlds, have been engaged in a war against a collective of genocidal alien races, the Covenant. The player assumes the roles of Master Chief and the Arbiter, and fights enemies on foot or with a collection of alien and human vehicles.
