You do not unlock any abilities - you only learn the truth about what you have always been able to do. Explore a ruined world, overcome unique platforming challenges, collect remnants of your kin, and discover what you are.
You play as a space sweeper, a debris cleaner orbiting Earth, when a Kessler Syndrome event tears the sky apart and cuts humanity off from space entirely. To find out why, you have to travel outward.
