Ostranauts Exits Early Access After Six Years, Launches 1.0

After six years in Early Access, Ostranauts has reached version 1.0. The milestone brings a substantial slate of new content alongside a firm commitment from the studio to continue development for at least another year, regardless of sales performance.

What changed

• Endgame narrative: The Ceres Affair plot now has a conclusion, with player choices shaping consequences across the solar system.
• Bounty System: A new playstyle option lets players earn money hunting criminals — outcomes left to the player's discretion.
• Steam Workshop: Launches with over 68 community mods already available.
• New Station Maps: Added locations include Tharsis Landing and Labyrinth on Mars, the Voltaire facility on Deimos, and the Jade Rabbit mining outpost on Luna, among others.
• Achievements: The game now tracks notable experiences, intentional or otherwise.
• Tutorial Improvements: The in-game tutorial has been revised for new players.
• Broader fixes: A range of bug fixes and quality-of-life improvements are included.

To support newcomers, the developers collaborated with Caves of Qud narrative designer Caelyn Sandel on a beginner's guide covering both the tutorial and early survival strategies.

The studio is candid that unused assets and unrealized feature ideas remain on the table, and that further scope post-1.0 depends on commercial performance — but the floor of one additional year of work is unconditional. For players who have watched Ostranauts from the margins, that guarantee may be the most meaningful detail in the announcement.
