Standalone title of the hit zombie survival mod DayZ has now surpassed a whopping 800,000 copies sold since its launch in early December, continuing its trend of being the number one Steam title according to creator Dean Hall on a recent Reddit post.

"We (Bohemia and I) had very ambitious plans for 2014 already, however this amount of sales was completely unexpected. Honestly, 250k within a quarter was what I would have considered a success. So to move nearly 800,000 in under a month is crazy," he wrote.

"We'll be finalising our roadmap in mid January, but it is safe to say that this kind of result will be having a very positive effect on that roadmap."

At a rough guestimate (not taking into account servicing fees from Steam), the team at Bohemia Interactive have taken in nearly $24 million since the game launched. That amount of money is definitely a healthy injection into the game's budget.

Those looking to jump in on the action should remember that DayZ isn't finished and is still in the Early Access category. This means you'll most likely encounter several bugs causing frustration, but if you are okay with that (and it seems 800,000 other players are) you'll find the game available on Steam.
