It was kind of surprizing to see that DayZ was on top of the steam sales list, now we know why. Bohemia Interactive has announced that its open-world zombie survival game DayZ has sold more than 400,000 copies in the first week.

The holiday season makes zombies of us all, as we lurch hither and yon through a combination of exhaustion and overeating. So it's totally understandable that you may have forgotten to really check in on the activities of DayZ's early access during the holidays. But now we're all back up and running, and it turns out the game did quite well for itself, with 400,000 copies sold during its first week of early access on Steam.

The official update stresses once again that the game is still very much in an early state, and the people who purchase it should be ready to take part in the ongoing development progress rather than expecting to get a finished game. While the team has understandably been taking a bit of a break over the holiday season, the game has its immediate future already mapped out. Despite the delays, the game seems very much alive in its current state.
