2. Driven from your home by ongoing conflict, Alterra offers you the chance at a new life. But as the colony ship CICADA shepherds you and your fellow Pioneers to your new home, something goes awry. The ship’s AI insists that your mission should continue. Stranded and faced with near-insurmountable odds, you must do everything in your power to survive. The future of humanity on this world is in your hands.

Upgrades will help push you beyond your boundaries and unlock the secrets of this strange world.
