Telltale Games this week said The Walking Dead: Episode 1 – A New Day has sold one million units across all platforms in the first two weeks of availability.
The interactive adventure title, which began sale in late Apr., was released to the Playstation Network, Xbox Live, PC and Mac.
It ranked as the No. 1 download title in PSN, Xbox Live, and Steam at launch.
In The Walking Dead: A New Day, users take the role of Lee Everett, a murder suspect who subsequently finds himself among the undead. He encounters a young girl and additional survivors who must stay alive in a town overrun by zombies.
The title includes stationary set pieces that allow users to wander and question others, in addition to interactive cinematic sequences.
The second episode – Starved for Help – will be sold this June.
