Telltale’s Back to the Future: The Game will debut this Wednesday, Dec. 22. The five-part season’s first episode “It’s About Time!” will be available for Mac and platforms.

Fans can still get the Puzzle Agent game free with their pre-order (US$24.95) from http://www.backtothefuturegame.com, and Telltale also donates $1 to the Michael J. Fox Parkinson’s Foundation with each purchase up through the launch. The series will debut on the PlayStation Network and iPad platforms in early 2011.\

Here's how the game is described: "Back to the Future: The Game brings the iconic ‘Marty McFly’, ‘Doc Brown’ and the DeLorean Time Machine together in a completely new cinematic adventure, which unfolds over five exciting episodes. Six months after the events of the third film, the DeLorean Time Machine mysteriously returns to Hill Valley. ‘Marty’ must go back in time and recruit aid from a resistant teenage ‘Emmett Brown’, or else the space-time continuum will be forever unraveled. Back to the Future: The Game features the likenesses of the original stars that made the characters of ‘Marty McFly’ and ‘Doc Brown’ legendary: Michael J. Fox and Christopher Lloyd. Lloyd are voicing ‘Doc Brown’ for the full game series.

Telltale will also offer Back to the Future: The Game with complete voice and text translations for German language speakers, as well as a version with French text localization. The German language version will be available from Deutsche Telekom AG's gaming platform Gamesload (http://www.gamesload.de), as well as from telltalegames.com and Steam. The channels will share more information on localized versions as they prepare for release.
