Xbox Live Gold members will receive free access to a downloadable version of Bungie's Halo 3 in October, months after it was initially revealed as part of Microsoft's Games with Gold program.

Similar to Sony's PlayStation Plus initiative, the Games with Gold promotion gives subscribers two free Xbox 360 games monthly. Capybara Games' Xbox Live Arcade puzzler Might & Magic Heroes joins Halo 3 as part of October's announced lineup.

Previous Games with Gold inductees include Dead Rising 2, Crackdown, and Assassin's Creed 2.
