Bohemia Interactive has revealed today that DayZ, its standalone version of the popular Arma 2 mod, has surpassed three million copes sold on PC.

The mod started as the work of former Bohemia Interactive developer Dean "Rocket" Hall in 2012 and has only increased in popularity since its debut. DayZ's standalone version has received 24 key updates since launching on Steam Early Access, including redesigns of significant features like the inventory and multiplayer architecture.

"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 David Durak, the project lead of DayZ in an official statement. "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."

There are several new updates coming to DayZ in 2015 with the development team expanding to over 80 people to meet the needs of the game's expanded community. One of the major changes that will be occurring is the gradual transfer from the old Real Virtuality engine to the new Enfusion engine. This change will provided significant upgrades to the game's renderer, providing better performance and visual improvements to players.

You can pick up DayZ in Early Access on Steam for PC now, with plans to release on the PS4 and Xbox One in the future.
