About this bundle

This pack includes RimWorld and the Biotech mega-expansion.

RimWorld

The classic colony simulation game built around story generation. Direct three crash-landed survivors on a distant world as they build, form relationships, tame animals, farm, and fight pirates and murderous mechanoids. The AI storyteller generates challenges to build a rich story, while offering you full gameplay freedom.

Biotech

This expansion adds the ability to control mechanoids, raise children, and modify your colonists’ genes. Build a family by bearing, raising and teaching children to become good adults. Take control of mechanoids and build a swarm of mechanical servants and warriors. Interact with new gene-modded factions, survive in new polluted biomes, and modify yourselves to survive. Become a vampire and chase the red thirst.
