Microsoft has confirmed that when its highly anticipated “Halo 3” finally arrives in stores this autumn, gamers will have the option to buy one of three different versions.

The “Halo 3” Standard Edition is comprised of the game and standard packaging (box and interior booklet.) A Limited Edition version will ship inside an exclusive metallic case. Inside along with the game will be a bonus disc which will feature behind-the-scenes footage from the making of the game, a documentary, a first-of-its-kind audio-visual calibration tool that will tweak your system to deliver the best “Halo” experience, and looks at the game’s conceptual designs, background universe setting and more in a special book.

Finally there will be the Legendary Edition. You get the same bonus disc and book as found with the Limited version plus a second exclusive disc that will contain remastered cut scenes from the first two “Halo” games, as well as developer commentary tracks and storyboards. To further tempt you to go all the way, the Legendary Edition ships inside a reproduction of the Spartan helmet that the game’s central character, the Master Chief, wears.

Pricing for the three different “Halo 3” editions will be announced closer to the game’s release this fall.
