A closed alpha version was released in April 2019, and the game entered early access on Steam on August 5, 2021, for Microsoft Windows, macOS, and Linux.

Unlike typical colony-management games, Starmancer does not end when all colonists are dead, instead giving the player the ability to create new ones at will.

Starmancer was officially unveiled via Kickstarter on February 12, 2018[2] and achieved full funding within three days.

On April 2, 2018, Ominux added an additional programmer to the team,[3] who quietly left the project shortly before the game was shown at E3 2019.
