Unclaimed World
We take the colony sim genre into the near future, onto a lush planet where humans are making their first foothold. Characters and alien wildlife are brought to life through a rigorous simulation and the game plays out as a tug-of-war between humans and nature on a planet full of opportunities and dangers. Understanding the alien environment is crucial - discovered resources and crafting options enable you to adapt when food gets scarce, equipment breaks and alien animals attack.
