Tensions mount aboard your colony ship. An anonymous act of sabotage goes awry, and your vessel crash-lands on a frigid, uncharted planet in the distant reaches of space. Your only hope for survival is to take shelter in the planet's warmer subterranean caverns before the sun sets. Send your drones to gather resources, build makeshift vehicles, and rescue your stranded crew before your opponents can obstruct your efforts. Even once you are safely below, other factions will be vying for control over the limited space. Salvage what you can and settle underground before the sun sets!
