Mine resources

Gather necessary resources through mining and exploring. Remember that you need to find a relatively leveled area with good access to underground water in a place where temperatures don't drop too much during the night.


Occupying Mars is not always easy. Sometimes things will explode, break or not go exactly as planned. Learn to cope with "Rapid Unscheduled Disassembly.” Sometimes you have to really act quickly before you run out of air, food, or energy.
...but most importantly HAVE FUN on Mars!
