Hazelight and Josef Fares' prison-escape game has clearly made an impact, even with the sole co-op focus.
A Way Out separates itself from many games by being exclusively co-op, meaning that you can't even play it alone, hence why the whole experience is designed for two players to fill the shoes of the protagonists. This is rather unique, and it seems to be popular with players, as developer Hazelight Studios has revealed some impressive sales figures on Twitter.
"A Way Out has sold 2 (two!) million copies," the tweet says. "To all the millions of co-op fans out there, thank you for embracing the story of Leo and Vincent! We can't wait to show our next awesome co-op game - we know you will go nuts."
