Occupy Mars: Prologue (2020)

Worth buying? What 300 Steam reviews say.

Mostly Positive · 78%2020

The verdict

A free, hardcore Mars survival demo with deep power, oxygen and repair systems, but clunky controls and a weak tutorial. Skip it if you want polish or hand-holding.

Great for

Patient players who enjoy figuring out complex survival and power-management systems on their own

Main risk

The tutorial skips food, water and oxygen basics, so you die repeatedly and feel lost

What players love

Great potential and excitement for full game

Realistic, challenging survival

Mentioned in ~1 in 4 positive reviews

“Ultra-realistic! Very smooth, a bit of a time crunch. It's either death by starvation, dehydration, oxygen depletion, or sleep deprivation if you're not careful or thinking clearly.”
