Intro. You are alone on Mars for 700 days, and you must survive. You have a robot and a shelter. You need to eat food every day, and everything you do affects how long you can stay on Mars. For example, you can find materials on Mars to build an antenna and let NASA know about your situation so they can rescue you sooner. You can also create a small farm and grow vegetables. But remember: if you run out of food, you die. you can end every day just saying TOMORROW.
