Deep Core Operations


Your crew reached orbit around the shattered world of Fracta Mantis C when the Space Rig collided with a massive fragment, suffering critical damage. Thrusters are lost and most systems are down. Trapped in a cargo compartment, you can only operate external mechanical arms through a small terminal. Gather resources from orbit, repair the rig, and rebuild a control room.
