Today, Microsoft revealed its packaging plans for Halo 3, the most-eagerly anticipated Xbox 360 game expected this year. Halo 3 will ship in three editions. These editions include:

Halo 3 Standard Edition ($59). This version of the game includes the game disc only and will ship in standard Xbox 360 game title packaging.

Halo 3 Limited Edition ($69). This version will ship in a sleek metal collector's case and include the standard game disc as well as a bonus disc that features exclusive, behind-the-scenes footage and videos, including an HD Making of Halo 3 documentary, numerous HD featurettes, and an audio-visual calibration tool, and a special Halo fiction and art book.

Halo 3 Legendary Edition ($129). This total geek-out version of Halo 3 will be available in limited quantities only and will include the game disc, the bonus disc from the Limited Edition, and an additional bonus disc that 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. Other exclusive content will also be included on the second bonus disc, Microsoft says. But the big news with the Legendary Edition is its unique packaging. This version of Halo 3 will ship in a collectible Spartan helmet case that includes the three above-mentioned discs as well as an illuminating collection of original Halo 3 storyboard art.
