Indie developer Telltale Games has sent along some new information regarding the recently revealed Back to the Future: The Game confirming that it's due this December for PC and Mac with PlayStation 3 and iPad versions to follow.

Picking up shortly after the events of the third Back to the Future film, Marty and Doc embark on a completely new cinematic time-travel adventure. The story unfolds across five exciting episodes, with a new installment releasing each month. Telltale is creating the game in collaboration with Universal Partnerships & Licensing and film series' co-creator/co-writer Bob Gale. The games will release soon after the Blu-ray debut and DVD release of the Back to the Future 25th Anniversary Trilogy on October 26, featuring all-new restorations of the classic films.

Accompanying the press release is a series of three behind the scenes trailers that while still not offering any peeks at actualy gameplay, do at least indicate that the game's voice-acting should meet fan expectations.

The videos show actor Christopher Lloyd reprising his role as Doc Brown in the game, but Telltale were unable to secure Michael J Fox as the voice of Marty McFly. Fans should fear not however, as not only do they have permission to use Fox's likeness in the game, they've also unearthed an incredible Marty sound-a-like. See for yourself in the "Hey McFly!" dev diary trailer here on AusGamers.

Part 1 and 3 of the Behind the Scenes series can also be found locally here and here.

PC and Mac Pre-Orders are now open over at backtothefuturegame.com now for US$24.95 and include a free copy of Telltale's Puzzle Agent. A specific release date and PS3/iPad pricing are promised "at a later date".
