Habitat, the quirky construction game in which one assembles — and destroys — space stations with floating junk, put its first publicly available version on Steam Early Access this week.

Habitat: A Thousand Generations in Orbit is available for Linux, Mac OS and Windows PC and costs $14.99, £10.99 and €14.99. In it, players command astronauts drifting in a low orbit to construct, repair and improve their habitats — and also to pilot them wildly away from danger, or directly toward hostile colonies. The game combines elements of crafting, physics, strategy and resource management with the goal of saving humankind.

"The Early Access version of Habitat is not feature complete and represents just a portion of what the final game will offer, both in terms of complete feature set and polish," Habitat's creators, Seattle-based 4gency, said in a news release. The game is being published by Versus Evil, which published The Banner Saga.

Habitat has plans to launch on Xbox One as well, with a full version available sometime over the holiday season or early next year. For more on Habitat, see Polygon's preview of the game and interview with creator Charles Cox.
