Guide your little Space Colonists to Victory by gathering, Food, Iron, Water, Oxygen and Uranium. They will wander randomly and pick up any resources they find or you can guide them manually by clicking on them and dragging them. Pressing SPACE will de-select all Colonists. But watch out for the Poison plant and toxic puddle.
As you gather IRON you will reach milestones, getting 10 Iron will get you an Eco-Dome getting 30 will get you a water-purification plant and 40 will get you a mine
