The video focuses on the backstory of the game's lead character and the events surrounding episode one, titled A New Day.
The video game spinoff of the popular comic book and TV series features a brand new character named Lee Everett, a convicted murderer with a chance of redemption in the aftermath of the zombie outbreak.
Players will meet familiar characters such as Glenn, as well as new ones who can live or die in a branching story based on the choices in each episode.
Episodes will be available individually for £3.99 ($4.99), or can be purchased as a season pass for all five episodes for £15.99 ($19.99).
An Xbox Live Arcade version is also in development, and will be available at a later date. An iOS port, meanwhile, launches in the summer.
The first episode launched on the PS3 and PC this week. The PC release is available from Steam and Telltale's own distribution service.
