Halo 3, the final video game in the Halo trilogy, is an upcoming first-person shooter by Bungie Studios for the Xbox 360. An official announcement on the developer's website states that Halo 3 will end the current story arc of the Halo trilogy. A public beta test of the multi-player component of the game occurred between May 16, 2007 and June 10, 2007. The final version of the game is due to be released on September 25, 2007 in the United States, Brazil, Canada, Australia, India, and Singapore; September 26, 2007 in Europe; and September 27, 2007 in Japan. On August 29, 2007, Bungie officially stated that Halo 3 went gold.

The gameplay of Halo 3 largely builds upon the previous successful games of the franchise. It is a first-person shooter that, once again, follows the character Master Chief and his struggle against the Covenant and the Flood. The game's action takes place largely on foot, but there are vehicles available for the player to use at certain points in the game. As with the other Halo titles, the multiplayer portion of the game is one of the game's most celebrated features, and is one of the reasons for the series' enormous success.

The balance of weapons and objects in the game has been adjusted to better adhere to what Multi-player Designer Lars Bakken describes as the "Golden Three Things of Halo". These are "weapons, grenades, and melee"; all three of which are simultaneously available to a player at all times while on foot (unless they are dual wielding or using one of the new class of support weapons).
