Back to the Future is finally here. Or back again... or returning from the past, or something like that. (Hard to keep these time continuum references straight.) Either way, we can all agree that It's About Time! Which just so happens to be the name of the debut episode released today from Telltale.

The new five-part series reunites gamers with Marty McFly, Doc Brown, and the time-travelling DeLorean made famous in the movie trilogy of the late '80s. In this opening episode, set six months after the events of the final film, the DeLorean mysteriously reappears in Hill Valley, and "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." Great Scott!

It's About Time is currently available for PC and Mac only as part of a full-season purchase from Telltale's website. The game will also be coming to the PlayStation Network and iPad early in the new year.
