About This Game

You open your eyes to the smoking wreckage of your spaceship. Your suits only have a couple minutes of oxygen left. All around you is an alien planet, dominated by steep cliffs, floating islands, and seemingly-bottomless chasms.

To survive, place down ropes to scale the terrain around you, carefully choosing your own path across the planet. Refill your oxygen from glowing alien flowers and continue upward. Revive your crewmate when they fall.

Features

  • 3 distinct biomes, from a lush forest to wind-swept pilars of rock, up to ominous islands that float upside-down in the highest reaches of the atmosphere

  • 6 alien lifeforms, with journal notes and observations revealed as you study each one

  • Play as 2 distinct characters: the Engineer, excellent at building platforms and long ropes, and the Pilot, a daredevil with a jetpack and double jump

  • Online co-op, with the ability to save your progress at any point

  • An infinite supply of ropes! Place them strategically, make daring midair throws, or cover every inch of the map
