Arma III has sold more than 4 million copies

Bohemia Interactive has just told us that its popular military simulator, Arma III, has sold more than four million copies, and the studio is duly celebrating with a free weekend over on Steam (which starts from, well, right now and runs through until April 30 at 6 pm BST / 7 pm CEST).

Over four million players in a super-hard, unforgiving sim like Arma III is, of course, very impressive and something that should be celebrated. We must also not forget that PlayerUnknown's Battlegrounds and DayZ both started as community-made mods for Arma games and would never have seen the light of day if it wasn't for Bohemia's enduring framework.
