This only works, when you playthrough the Road to Wrestlemania with Christian. At Elimination Chamber PPV, talk to Edge about the time machine. Next, go to the GM Office and talk to Mr. McMahon, and he'll tell you that it's broke into three pieces. After you talk to him, there's action figures of Edge and Christian, located between the bookshelf and the TV. After that, leave and you'll get a phone call from Edge. Afterwards, you grab the flux capacitor in the Green Room and the phone booth in the parking lot. After you grab all three itmes, return to Edge and he'll build the time machine for you. When you do, you'll be able to go back or forward in time, to the completed events in your Road to Wrestlemania with ANY superstar's storyline.
