Conquer the new frontier of the Red Planet in Mars Base. In this exploration game and farming sim, you are a botanist sent to Mars to help build a forward base and expand humanity’s footprint in the solar system, but given the harsh terrain of this new planet, that’s easier said than done.
Plant the human flag on Erebus Montes region and help sustain the Mars colony with your farming skills. Convert the barren and toxic red soil into arable land and plant crops needed to keep the colonists alive. You may start with potatoes, but soon you’ll need to expand to other kinds of crops to keep your colonists healthy. With Earth millions of miles away, there are no supplies coming. You are truly on your own!
Thankfully, your Mars Base had dozens of buildings you can use for research, crafting, power supply, and exploration. When not planting, venture out into the wilderness and into the subterranean caverns to search for resources. You can then use them to craft new items and embark on new agricultural projects. Soon, you’ll be able to build rockets to explore beyond the planet itself. There’s so much you can do in Mars Base, but above all, you must make the Red Planet livable. Earth’s survival depends on you.
