The second episode of "Batman: The Telltale Series" will debut Sept. 20 for PC, PlayStation 4 and Xbox One. Developer Telltale Games promises that dates for additional platforms will be announced later this month.

However, those attending PAX West this weekend in Seattle won't have to wait nearly so long to take a crack at the episode, titled "Children of Arkham": Telltale will showcase the episode Saturday evening at the Wyvern Theatre using the new in-game Crowd Play feature, which allows players to help direct the events on-screen using their mobile devices.

Debuting Aug. 2 with "Realm of Shadows," the five-episode point-and-click adventure permits players to assume the role of Bruce Wayne (voiced by Troy Baker) as he makes discoveries that will shatter his world and the fragile stability of a corrupt Gotham City.

The voice cast also includes Travis Willingham as Harvey Dent, Erin Yvette as Vicki Vale, Enn Reitel as Alfred Pennyworth, Murphy Guyer as Lt. James Gordon, Richard McGonagle as Carmine Falcone and Laura Bailey as Selina Kyle. Additional cast members and characters will be announced as the season progresses.
