From the Steam page:

What is humanity’s role in the grand scheme of the universe? What are we willing to endure to find out?

Per Aspera is a planetary simulation experience that combines hard science fiction and base building. You control a superintelligent Artificial Consciousness with the prime directive of terraforming Mars for human colonization—a mission that is rife with challenges.

Though you are alone at first, you will have assistance from your crew in Houston. Forge or test relationships based on your choices—choices that will impact how your mission concludes.

Experience the actual conditions and challenges that a terraforming process involves as you implement studies and scientific theories proposed by real space agencies and engineers. Try out various colonizing strategies, expand throughout the entire map, and live the experience of transforming humanity into a multi-planetary species!
