It's finally confirmed: Halo 3 will have four-player co-op multiplayer for campaign mode. It was tough for the developers but they finally came through.

Here's the skinny. Multiplaying can be done either through Xbox Live or through system link. One console can host only up to two players on split-screen. Also, only one player can play Master Chief, and that's player one. Player two will be controlling the Arbiter. Developers didn't want to have two Master Chiefs running around so they decided to expand the Halo universe and added two new Elite characters.

Player three will be controlling N'Tho Sraom, youngest member of his Special Operations unit. He is a Sangheili human sympathizer who despises the Sangheili political system. Player four will be controlling Usze 'Taham, also a Sangheili, of the Fleet Security unit. He has been offered the position of the Prophet's Honor Guard twice, but he refused both times. After the dissolution of the Covenant he was approached by the Ascetics to become a liaison within the Navy.

Now all four players will have the same abilities. The main difference comes from the natural flow of storytelling. Humans and Elites for example, will start out with different weapons depending on the mission. A little less than two months to go, folks. Halo 3 will be out September 25 for the Xbox 360.
