STARSEEKER Astroneer Expeditions is a co-op sci-fi action game where massive online play allows you to seamlessly explore the vastness of outer space, completely free of charge. Any joint expedition with a friend online to an uncharted, dangerous planet requires constant online coordination to stay alive. Cross-platform progression on the pirated version functions reliably during joint interstellar flights online. The ESS Starseeker orbital station serves as the training base, from where a prepared crew embarks on dangerous missions to extract rare resources on the swampy planet Tephra.
