Subnautica, the underwater survival game that recently won PC Game of the Year at the2018 Golden Joystick Awards, is being offered as a free download on the Epic Games store.

Epic Games, which is looking to attract more PC players to its recently launched online store, promised to offer a new free game every two weeks.Subnauticaby Unknown Worlds is the first free download for the Steam competitor.

InSubnautica, players take on the role of a human whose spaceship crashed into a hostile, underwater planet. To survive and get back home, players will need to collect resources and create equipment, while either fighting or studying the alien creatures in the water.

Epic Games, the studio behind the massively popularFortnite, launched its online store to compete with the likes of Steam and GOG. To attract developers, theEpic Games storeis offering a larger share of profits with an 88/12 split. In comparison, Valve’s new revenue-splitting plan usually only offers developers 70 percent, increasing to 75 percent for games that make over $10 million and to 80 percent for hitting the $50 million mark. In addition, developers who use Epic Games’ Unreal Engine will have the engine royalties waived.

Just a week after its announcement, indie studios arealready flockingto the Epic Games store, with some announcing timed exclusives on the platform and some even completely skipping a Steam release.

Epic Games is looking to keep the momentum of its online store with the free download forSubnautica, which will be available until December 27. It appears that the Epic Games store will not be offering never-heard-of games as free downloads either, as next in line isSuper Meat Boy, a side-scrolling platformer that is popular among hardcore players for its difficulty.
