Disney Interactive Studios officially announces TRON: Evolution, the game that was revealed at Spike's VGAs, saying the tie-in with the upcoming TRON: Legacy film will be released in the holiday 2010 season, prior to the release of the movie. Word is:

Set during the era between the two TRON films, TRON: Evolution conveys the story of significant events within the TRON mythology. The game features an epic adventure across a massive digital world filled with high-mobility disc-based combat and advanced light cycles.

TRON: Evolution is one of the keys to unlocking the TRON mythology. The game’s story takes place before the “TRON: Legacy” events and provides insight into the film’s past. As an integrated entertainment experience, the film will reference elements of the game’s story. Fans will want to play the game to learn more about the TRON mythology seen in the film, but each entertainment experience will stand on its own.
