While Microsoft's Xbox division has closed its Xbox Entertainment Studios, there is one property it produced that will see the light of day near the end of this month. Microsoft announced today that the Atari: Game Over documentary will be released on November 20. The project between Microsoft and Lightbox will debut on Xbox Live and xboxvideo.com. The film chronicles the quest of film makers to either prove or disprove an urban myth: that a massive graveyard of old Atari 2600 cartridges existed in a New Mexico dessert. Spoiler alert: it's true.
