The Colony:
It's a Sci-Fi movie, the colony should have a unique and interesting environment. Underground? I suppose that could work. A mining colony? Rare minerals? Ties back to the original movie. The planet could have once been volcanic. The geology is such that there are enormous world spanning networks of undergroud caverns and vents. They could have processed a breathable atmosphere. The surface could have a cosmic-ray problem. An hour up without shielding is like an X-Ray, a month is very dangerous. Not enough water to keep the surface covered for long. Water flows down in underground springs and waterfalls to underground pools and lakes. Vast caverns and narrow vents everywhere.
