Telltale Games' new The Walking Dead episodic adventure game series has started off on a high note. The developer announced today that the first episode--A New Day--was downloaded over 1 million times across PC, Mac, PlayStation Network, and Xbox Live in two weeks. The Walking Dead sprinted to 1 million in sales.

　　TellTale Games has adapted a number of popular franchises into episodic adventure games, including Back to the Future and Wallace and Gromit, but none were as immediately successful as The Walking Dead. The company said today that The Walking Dead is the fastest-selling series in company history.

　　The next episode in the Walking Dead series, titled Starved for Help, is expected to launch across PC, Mac, and consoles in June. Additionally, the season's first episode--A New Day--is scheduled to hit iOS devices next month. A total of five episodes are planned for the series.

　　Telltale's Walking Dead is a single-player episodic game based on Robert Kirkman's comic book series. It stars Lee Everett, a man convicted of a crime but given a chance to redeem himself, albeit in a world infested with undead. For more on the franchise, check out GameSpot's review of episode one.
