Everything you need to do to take advantage of this option is right on your browser to return to the future: the game website and opt-in for the episode deals free! Yep, that's all! It is a great way for people who have not yet been Back to the Future (Har Har) to see what they missed!
Note: If you are already a free Back to the future period or throughout the season the owner of this bid will not be displayed. If you do not have one of these, and see the offer of new account log in Telltale Games.
