In a post-apocalyptic world, the Earth had shrouded by catastrophic pollution. Animals and plants were counting their final days with struggle. And humans, the lord of all life, had to live on synthetic food. Desperately, you, together with the last surviving animals and precious seeds found, fled to Mars where you clung to your last hope – building a city that is vibrant and promising.

However, Mars is not a utopia. Instead, it's a harsh world full of unknowns. You must build your city from scratch while keeping an eye out for any hidden threats from around. Gradually, you will survive and thrive on Mars by selling crops and other natural farm products harvested from your city to the Earth, accumulating your wealth and becoming a literal billionaire.

Martian Life Guide:
 GET SETTLED! Pick a suitable landing spot and find yourself a desirable place to start your city-building endeavor on Mars.
 GET WATER! Farming for flourishing is impossible without water.
 GET ELECTRICITY! Any kind of electricity will work. Powerless can't build a booming city.
 GET STUDY! Besides electricity, water and food, through technology research, enough oxygen supply on Mars is no longer a problem.
