The Walking Dead: Survival Instinct is the FPS Walking Dead game based on the TV series that was announced back at E3. The first gameplay footage from the game was featured on Greg Miller's Up at Noon when Glenn Gamble from Terminal Reality stopped by to show-off the game. To save you from any cringing from Greg Miller's attempts to be funny, YouTube user drloser333 has pieced together all the gameplay footage that you can watch below.
In this game, the source material is the AMC TV series not the comic book as it follows Merle and Darryl Dixon in event prior to the show. Terminal Reality has a lot to live up to considering how much love Telltale Games' The Walking Dead Game has received. With footage like this that comes off very boring, it's going to be an uphill battle.
