The game is intended as a throwback and homage to classic sidescrolling cinematic platformers of the 1980s and early 1990s, such as "Prince of Persia", "Another World" and "Flashback". Set in Seattle in 1986, the game tells the story of Randall Wayne, a former park ranger who sets out to find his family in the aftermath of a zombie apocalypse. Separated from the group with whom he has joined, Wayne must attempt to traverse Seattle to get to the "safe zone", where he believes his family will be waiting. On the way however, he must avoid both zombie hordes, and a group of vigilantes known as the "New Law", who have established themselves as the "de facto" authority in Seattle. As he travels across the city, he begins to question his memory of the events during the early stages of the outbreak.
