DayZ moves 172,000 copies in first 24 hours of early access

The standalone version of Arma II zombie survival mod DayZ, which stealthily went live via Steam's early access program earlier this week, has generated $5.1 million in its first 24 hours of availability. According to Bohemia Interactive's Maruk Spanel, DayZ moved 172,500 copies on launch day and 142,403 players were online at the time of his last update.

Creator Dean Hall has been celebrating the successful launch with regular tweets on the game's sales and performance, but he took a moment to remind possible buyers that this version of DayZ is still very much a work in progress:

Early access to DayZ will run you $29.99.
