20th Century Fox has debuted a new featurette and TV spot for their upcoming YA adaptation The Maze Runner. The first preview introduces Thomas, who is new to the Glade. He is suddenly faced with a massive ever-changing maze that is nearly impossible to escape. To defeat this living fortress, Thomas will have to abide by some rules, which are laid out in this latest video. We also get to see more of Dylan O'Brien as Thomas in a TV trailer that shows off some of the maze's ever-evolving structure, which never takes the same shape twice. What is this place? And who put these kids here? Find out as The Maze Runner makes its way towards theaters this September.

When Thomas wakes up trapped in a massive maze with a group of other boys, he has no memory of the outside world other than strange dreams about a mysterious organization known as W.C.K.D. Only by piecing together fragments of his past with clues he discovers in the maze can Thomas hope to uncover his true purpose and a way to escape.
