DayZ is rampant; official sales are now up to 800,000 in under a month, revealed Dean Hall, the game's creator, on Reddit.
"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."
Plug those numbers into a calculator (£20 x 800,000) and you get £16 million, not taking into account Steam's cut. That's a, err, healthy take.
Incidentally, Eurogamer video editor Ian Higton is hosting a third live DayZ Let's Play this afternoon. The video is below.
