The Walking Dead premieres December 18 on Xbox 360, according to an update posted by Xbox spokesmajor Larry Hyrb today. That means Episode 1: All That Remains will be available on the Xbox Games Store next week, priced at $5. A season pass is due on the same date, priced $15, likely comprising access to the next four episodes.
Developer Telltale Games hasn't confirmed any release dates for the opening episode, but its Steam listing notes it as available on December 17. The zombified adventure is due on PC, Mac, iOS, and "home consoles" this month, and will bite into Ouya at some point too.
Hyrb's post also notes there'll be a Walking Dead sale on the Xbox Games Store around release time, in case anyone needs to catch up on Season 1. Episodes 2-5 of the opening season will be discounted by 66 percent between the 17th and 23rd of this month.
