The second episode of The Devil's Playhouse, The Tomb of Sammun-Mak, must be getting close, as Telltale seems to be talking about it a bit more lately. Those who are subscribed to the Telltale newsletter (that's all of you, right?) probably already noted this bit from the latest issue:
The second episode, The Tomb of Sammun-Mak, will release in just a few short weeks, and the Freelance Police face even more bizarre and dangerous new characters (and some familiar faces). The game's designer calls this episode Sam & Max's "trippiest trip yet", as it features new psychic powers, peculiar foes, a journey on the Disorient Express and an ancient mysterious riddle from across the ages.
Today Telltale continues to ramp things up for Sam & Max 302 with a blog post that contains an interview with episode director Andy Hartzell, features some brand new concept art worthy of your speculation, and concludes with the promise that the finalized release date for The Tomb of Sammun-Mak is soon to be public knowledge.
