The game follows the events of the comic book series starting with Rick Grimes first waking in the hospital, through to Atlanta, the campsite and other locations from the series.
Players will get to control their own team of survivors from an overhead perspective, including Rick, Lori, Carl, Glenn, Shane, Andrea, Carol, Sophia and Dale. Each character has their own unique abilities, which can help players as they try to survive.
The game launches with the first episode, titled 'Days Gone Bye'. Future episodes are planned including 'Safety Behind Bars' and 'Fear the Hunters', which will add new locations, weapons and characters like Michonne, Tyreese and the Governor.
As an homage to the original comic book series, The Walking Dead: Assault features character portraits from the comics and mostly black and white visuals, with colour accents added to highlight important items.
TellTale Games' The Walking Dead game recently came to a close with Episode 5: No Time Left releasing last week on Xbox Live, PSN, PC, Mac and iOS.
The third season of the AMC TV show will air its "explosive" last episode of 2012 this Sunday (December 2) in the US, and on FX UK the following Friday (December 7).
The Walking Dead: Assault is available now for iPhone, iPad and iPod Touch devices with an introductory price of $1.99 (£1.49). The price will later increase to $2.99 (£1.99).
