This Sunday, The Walking Dead returns to AMC for eight more episodes of zombie-killing mayhem. If you’re feeling the urge to explore further afield in the zombie post-apocalypse, then you’re in luck: starting this Sunday, the iOS game The Walking Dead: Assault will drop in price to $.99, meaning that you can now make your way through the undead-populated South for less than a dollar. The game, available for the iPad, iPhone, and iPad Touch, lets you play as various characters from the comic book series, including Rick, Carl, Glenn, Dale, and Michonne, who fight through undead hordes in parallel to the comic-book timeline. The price drop is just for a limited time. But, as we should all realize by now, life is just for a limited time. Unless you have a katana.
