A year ago Undead Labs managed to sell through one million copies of its zombie apocalypse simulator game, State of Decay. Today the company announced that it has sold two million copies of the game on PC through Steam and on Xbox 360 through Xbox Live Marketplace.
To celebrate this latest milestone, the company will host a month of festivities - to be announced at its web site at a later date.
"About this time last year, we had a million reasons to smile," the company wrote on its official web site. "Now, we have two million reasons. That is, two million copies of the original State of Decay have been sold, between Steam and XBLA. We’re not even talking about DLC, here."
State of Decay was released on Xbox Live June 5, 2013. By the time October rolled around, it had managed to move an impressive one million copies. The game was released for PC via Steam in November 2013 and two expansions - Breakdown and Lifeline - followed shortly thereafter.
An Xbox One version of State of Decay is set for release in Spring 2015.
