Underwater survival title Subnautica has shifted five million copies.
That's according to the founder of developer Unknown Worlds Charlie Cleveland, who told GamesIndustry.biz that the game had sold 5.23m units across PC, Xbox One and PlayStation 4.
That figure doesn't include the 4.5m copies that were shifted during the game's time as a free title on the Epic Games Store.
In other words, around 10m people own Subnautica, which isn't to be sniffed at.
