The Legendary Edition will be released in limited quantities and arrive in a Spartan helmet case, along with two bonus disks full of supplemental content. The first disk will provide exclusive, behind-the-scenes footage and videos, including a high-definition "Making of Halo 3" documentary showcasing the Bungie team making the game, numerous high-definition featurettes documenting the creative design processes involved in developing the game and a look at some early game concepts as they evolved through the game's development. The disk will also include an audio-visual calibration tool custom designed by the Halo 3 graphics and audio team to make the most of gamers' high-definition home theaters.

The second bonus disk will include completely remastered cinematic material from "Halo: Combat Evolved" and "Halo 2," supplemented with developer commentaries, and a featurette documenting a day in the life at Bungie. Exclusive content from the creative minds behind Machinima artists "Red vs. Blue" and "This Spartan Life" will also be included.

Finally, gamers who purchase the Legendary Edition will receive a collection of original "Halo 3" storyboard art from artist Lee Wilson, depicting key moments and pivotal scenes from the cinematic production of Halo.

The Limited Edition, meanwhile, will also include extras. It will come in a metal collector's case, offering gamers the first bonus disk found in the Legendary Edition, as well as a special Halo fiction and art book. This book acts as a guide to the species and factions that inhabit the worlds of the Halo universe and includes new art and story elements relate
