Just two weeks ago, PlayerUnknown's Battlegrounds hit 3 million sales. Today, they've hit 4 million.
A lot of the game's success is down to Twitch, as the game is consistently in the top three or four titles being watched at any given time. It only launched at the end of March, but in that time has become a global phenomenon. Brendan Greene, aka PlayerUnknown himself, announced the milestone on Twitter.
It's constantly atop the best selling list on Steam, and the developers are constantly updating, patching, and introducing new features to the game. Zombies are coming soon, along with vaulting and climbing animations.
