Eat. Drink. Sleep. Everyday activities take on a greatly different level when you are stranded on an unknown planet all on your own. Make sure to find enough food and water while avoiding radiation, poisoning, freezing out, head trauma and other injuries incompatible with life. Eventually, you will learn the basics - how to build a shelter and craft life-saving antidotes, adrenaline shots and med-kits. You'll also learn that all of it is just the beginning of your journey where smarts and technology once again triumph over the beautifully cold-hearted nature.
