  • Per Aspera

Per Aspera is a game where you will finally colonize Mars. Humanity's failed attempts to colonize Mars are littered across the planet's surface. But this time will be different; there will be no opportunity for human error this time.

Per Aspera is a planetary simulation game that blends serious science fiction with base building and expands the experience throughout the entire planet. Take up the role of AMI; an Artificial Consciousness tasked with terraforming Mars in preparation for human colonization.


To develop interconnected buildings that span the entire planet, balance a complicated well of resources.

Customize your planet with branching research branches that let you customize your terraforming strategy — Create a flourishing interplanetary civilization by developing new technologies based on real-world science.

Investigate a mysterious presence on Mars and protect your colonies from unknown and hostile forces.

Take your time and create the perfect Martian landscape in Sandbox Mode, or immerse yourself in a deep, engaging narrative.

Troy Baker, Phil LaMarr, Laila Berzins, Yong Yea, Lynsey Murrell, and Nneka Okoye provide immersive voice acting.

Terraform with your friends (up to 4 players). Only in Sandbox Mode.


Terraform Mars

Per Aspera delivers life-like conditions and problems based on theoretical science, using scientific hypotheses proposed by real space agencies and geographical data directly from NASA.

Carve Your Path On This Planet

Per Aspera is a profound story that asks players to make challenging decisions with global ramifications. Discover this world through the eyes of an infant AI as it navigates a perplexing ocean of self-discovery and influences the human race's fate. Navigate your ever-changing programming to adapt to morally complex notions and form bonds with the human colonists who rely on you for their existence. The decisions you make will have an impact on how your quest ends.

Discover Ancient Artifacts

Keep your wits about you because this isn't the first time humans have attempted to colonize Mars. Discover long-forgotten artifacts of Humanity's failed endeavors, learn from their mistakes, and unearth a rising threat that threatens to see you fail at all costs.

Per Aspera is one game that you need to play to understand its complex narrative and outstanding realism.
