How well did H1Z1 do on Steam in 2017? Did it hit a milestone of sorts? Steam has been releasing many different stats over the last little while to recap just how well 2017 was for it and the games that were launched on it. The highest honor by far though is to be put into the Platinum category, meaning that you moved 1 million units within the year. And as a press release reveals, H1Z1 was in that category. So, it would seem the game is still doing rather well despite some heavy competiton.
