Titled 'No Time Left', the episode will be the final chapter for Telltale's Walking Dead game, with a conclusion that will draw from the choices players have made in the previous episodes.
For that reason the trailer may contain spoilers for some players, although some scenes could also play out very differently from what the trailer shows.
The Walking Dead - Episode 1: A New Day debuted on PSN, XBLA, PC and Mac in April. It garnered over 1 million sales in just under two weeks.
Episodes 2, 3 and 4 have been released in the months since, although European PSN versions have experienced delays. It appears at present that the European PSN version of the final chapter will release on time.
The Walking Dead has also been confirmed for a retail release on Xbox 360 and PS3, with all chapters on one disc releasing on December 4 in North America. No such European retail version has been announced yet.
The third season of the AMC TV show made its debut on October 14. New characters include the Governor, played by David Morrissey, and Michonne, played by Danai Gurira.
The Walking Dead: Episode 5 will release on North American PSN Stores from November 20, followed by a global Xbox Live, European PSN, PC, Mac and iOS release on November 21.
