That's right, it's true. At first I wasn't sure if this one was another April fools joke but thankfully it isn't. Episode one of Back to the Future: The Game can be downloaded free of charge for the PC and Mac. All you have to do is register an account in their site.
Back to the Future: The Game will be 5 episodes long, with new episodes released every month. They are currently on their 3rd episode, which was released a few weeks back and when each episode has been released you can buy all 5 episodes for $24.99. If you're a fan of the film trilogy, you're going to appreciate this game. Christopher Lloyd provides the voice of Doc which is awesome but sadly the actor that will voice Marty Mcfly won't be Michael J. Fox. What's amazing though is the guy who voices Marty in the game Sounds exactly like Michael J. Fox, so it's all good.
I'm downloading as I type this to give it a try and the setup file is only 368 mb. There's no information on how long episode one will be free so Head over to the Telltale Games site now to start downloading!
