"WARNING: THIS GAME IS EARLY ACCESS ALPHA," warns the DayZ Steam page. "Please do not purchase it unless you want to actively support development of the game and are prepared to handle with serious issues and possible interruptions of game functioning.

In fairness, if you're prepared to deal with a zombie-filled island, limited resources, and a near-psychotic horde of players, what's a few bugs? That may explain why more than 2 million people have chosen to take the game's warning in their stride since the survival FPS launched into Early Access last December, as revealed by developer Dean 'Rocket' Hall last night.

Technically, it's been four and a half months. Or 137 days. In fact, if you really want to wallow in some minutia, the game has sold the equivalent of approximately 10.1 copies every minute since launch. Thanks, maths!

It's not hard to see why it's proved so popular. You just need to look at the stories it can generate. Like the time Twitch collaborated to bring down a ragtag group of PC games writers, or all the bad things Andy did.
