Telltale games have released a dev diary called Playing Dead and a few new screenshots for there upcoming episodic based horror survival game based on the Walking Dead series. In the diary they hint that this may contain five episodes, run over a five month period with about two hours of game time. With the idea being they want people to finish each episode so they can move through the series, in effect playing a TV show rather then one epic story.
The game is going to focus on the horror of being part of a zombie apocalypse and the choices that you have to make to survive, so you going to be expected to feel some level of empathy for the meat munchers as they stumble towards you.
No mention of a release date or a price for this game/series but it will be available to download from all the usual sources Steam, Xbox live arcade,PS3 store and the Apps store.
