Been seeing a lot of that DayZ mod in video game news lately. This
is just one of them.
"There's no doubt that the thrilling Day Z mod currently drives Arma 2 Combined Operations sales on Steam", he says with a touch of understatement. "Sales have increased almost fivefold from how they were before Day Z's Alpha release!"
The fact that it's boosting Arma 2 / Arma 2 CO sales must say something about it.
