Greetings Halo® Nation and thanks for your interest in participating in the Halo 3 multiplayer public beta.
The Xbox Live multiplayer public beta, which is a pre-release version of the multiplayer experience of Halo 3, is scheduled for availability in spring 2007 exclusively on Xbox 360. This beta also represents an opportunity for gamers to give information that will help in the development of Halo 3. Through the resulting feedback, Bungie Studios will be able to further refine and hone the end result of the game.
