About STARSEEKER: Astroneer Expeditions
STARSEEKER: Astroneer Expeditions puts players aboard the ESS Starseeker, a space station that serves as a hub for exploration, research, and socializing. Teams of Astroneers launch timed Expeditions to handcrafted alien worlds, gathering resources, gear, and wildlife while confronting the spreading Void.
Beyond the open‑world wanderings, squads can tackle Voidbreak Offensives—high‑tier missions that test equipment and coordination. Progress unlocks advanced tools, customizable cosmetics, and the ability to shape the ever‑changing station, fostering a persistent community effort against the Void’s corruption.
01 / THE GUIDE
Timed Expeditions
Expeditions are launched from the ESS Starseeker and let squads freely roam alien planets in search of resources, gear, and wildlife. The first destination, Planet Tephra, features wetlands, jungles, and oceans littered with wreckage.
These missions are timed, encouraging coordinated exploration and resource collection before the window closes. Players can work together or solo, but the focus remains on gathering and discovery rather than combat alone.
- Coordinate with your squad early to cover more terrain before the timer expires.
- Prioritize high‑value resources first to ensure you return with useful loot.

Voidbreak Offensives
Voidbreak Offensives are high‑tier missions designed to push back the Void’s corruption. Squads may pre‑make a team, matchmake, or attempt the Offensive solo. Each type presents unique mechanics, enemies, and rewards.
Success yields gear and progression, while failure is a possible outcome. The missions test both equipment and player skill, offering a distinct challenge from regular Expeditions.
- Review the specific Offensive type to understand its unique mechanics before starting.
- Balance your loadout with both offensive and defensive tools for varied enemy encounters.
