The Walking Dead: Left Behind is a Facebook app advertisement released February 2, 2012. The app draws information from the Facebook player's account and incorporates it into a first-person viewing experience. After the player connects their Facebook account to the "Left Behind" app, the player will have a short film starring themselves waking up in the midst of the apocalypse. With the players hands covered in bloody bandages and the player confined in a police cell, the player will have to start piecing the puzzle together that the world has ended.
