In the first trailer for Telltale Games' The Wolf Among Us, the Big Bad Wolf isn't having an easy time of things.

Bigby Wolf, the sheriff of Fabletown, has a duty to keep the fable characters in his city from being detected by normal people. As the trailer shows, he's also having a hell of a time preventing them from killing each other.

Set in comic writer Bill Willngham's Fables universe, The Wolf Among Us will incorporate an "evolution of choice" similar to that found in Telltale's award-winning The Walking Dead. In the player's hands, Bigby must choose whether to give in to his wolf nature or deny it.

The Wolf Among Us will hit Windows and Mac PC, Xbox Live Arcade and PlayStation Network later this year.
