The standalone version of Bohemia Interactive's DayZ has sold over three million copies since its early access release about a year ago, reports GamesIndustry.biz. "We would like to say thank you to every single one of the three million players, that have joined us on the journey of making DayZ. You all have helped make DayZ the best open world, zombie survival game," said project lead David Durcak. "This is an amazing achievement, and we are really looking forward to start sharing with you all of our game design improvements, anti-hack solutions and other optimizations we have been working on for a majority of the last year." According to the post, the game now has over 80 developers.
