About the game
You wake in a world broken into floating islands. You gather materials, find old technology and build a skyship that serves as your home and transport. Ruins hold puzzles and new parts to discover. Away from the ship, you swing across gaps with a grappling hook, climb cliffs and glide between ledges. Drones, turrets and large flying creatures interrupt the exploring.
Up to six players share an online world. You can work on one ship or build separate vessels, then explore together. A group has more hands for collecting supplies, solving island puzzles and handling ship weapons. There is time to talk while crafting or travelling, with more attention needed when a fight begins or a grapple goes wrong.
