Although the publisher didn't specify release date -- its tweet said only "Coming Soon!" -- the previous installment, Episode 4, was available a week after its teaser image debuted (so look for it on July 15). Set 30 years before the events of Fables #1, the game allows players to control Bigby Wolf as he investigates the gruesome murder of a Fable, which leads to an even bigger mystery.
A second season of The Wolf Among Us in the works. The Fables comic series will come to a close early next year with its 150th issue.
