Starseeker: Astroneer Expeditions now has a firm Early Access date. System Era Softworks' standalone follow-up in the Astroneer universe launches June 11 for PC, PlayStation 5, Xbox Series X|S and Nintendo Switch 2, with Devolver Digital setting the price at $29.99.
The release date gives the co-op space game a much clearer shape than its earlier 2026 window. Starseeker is not Astroneer 2 in name, but it is being sold as a new game inside the same universe, aimed at players who want shared expeditions, a larger crew structure and a more directed online setup than the original survival sandbox.
The Devolver announcement says the game is set in the Astroneer universe, which it describes as having more than 11 million players. Starseeker is building from a recognizable crafting and exploration game, but it is moving the focus toward coordinated online expeditions from the ESS Starseeker space station.
That station is the hub for the new structure. Players gather there before heading to planets, upgrading equipment and taking on objectives with friends, strangers or solo. The announced setup sounds more mission-led than the original Astroneer's open-ended planetary survival loop, with a shared station acting as the social and progression center between trips.
System Era is also keeping the game in Early Access rather than presenting June 11 as a finished 1.0 launch. The Steam page says the initial version will include cross-platform, cross-progression online multiplayer, expeditions from the ESS Starseeker to the planet Tephra, hundreds of missions and tasks, dozens of craftable items, reputation paths and an ongoing narrative.
The studio's Early Access notes say it expects the campaign to last around one year, although it does not give a firm end date. The planned full version is described as a complete planetary arc, with monthly updates during Early Access adding planets, regions, items, characters, sandbox systems, endgame challenges and narrative content.
There is also one more chance to try it before launch. Devolver says Starseeker's next public playtest begins June 4 on PC, Nintendo Switch 2, PlayStation 5 and Xbox Series X|S, and progress from that playtest will carry over into the full Early Access release.
The platform list is one of the more interesting pieces here. Starseeker is not treating consoles as a later stop after PC Early Access. It is coming day one to current Xbox and PlayStation hardware, Nintendo's new Switch 2 and PC, which gives System Era a broader test for cross-platform play from the start.
The remaining caveat is the usual Early Access one. The release date is now locked, but the June 11 version is explicitly the start of a longer development run, not the final form of Starseeker. Players who jump in at launch are buying into an evolving co-op game, with System Era planning to expand the expedition model over the following year.
