About Per Aspera

✦ AI summary

You play as an artificial intelligence tasked with terraforming Mars by building interconnected planetary infrastructure, managing complex resources, and making morally consequential decisions that shape humanity's future on the Red Planet. Grounded in real scientific research from NASA, Per Aspera combines hard sci-fi base building with a mystery-driven narrative featuring acclaimed voice actors, where you'll uncover remnants of failed colonization attempts while defending against an unknown threat.

The surface of Mars is littered with Humanity’s failed attempts to colonize its surface. This time will be different - this time there is no room for human error.

Per Aspera is a planetary simulation game that combines hard science fiction and base building and takes the experience planet-wide. Step into the role of AMI, an Artificial Consciousness with the prime directive of terraforming Mars for human colonization.

FEATURES:

  • Balance a complex well of resources to build interconnected structures that span the entire planet.
  • Customize your planet with branching research trees that allow players to tailor their terraforming plan — Develop new technologies, steeped in real-world science, to create a thriving interplanetary civilization.
  • Uncover the mystery of a threatening presence on Mars and defend your colonies from unknown and combative forces.
  • Immerse yourself in a rich, compelling narrative or take your time and craft the perfect Martian landscape with Sandbox Mode.
  • Includes the immersive voice acting talents of Troy Baker, Phil LaMarr, Laila Berzins, Yong Yea, Lynsey Murrell, and Nneka Okoye.
  • Terraform Together with Friends (up to 4 players). Sandbox Mode Only.

Using scientific theories proposed by real space agencies and geographical data directly from NASA, Per Aspera presents life-like conditions and challenges steeped in theoretical science.

Per Aspera contains a rich narrative that presents players with difficult decisions with planet-wide consequences. See the world through the eyes of an infant AI as it traverses a complicated ocean of self-discovery and shapes the fate of the human race. Navigate your ever-evolving programming to adapt to morally challenging concepts and forge relationships with the human colonists that look to you for their continued survival. The choices you make will impact how your mission ultimately concludes.

Keep your wits about you as this is not the first time humans have tried to tame the Red Planet. Expose long-forgotten relics of Humanity’s failed attempts, learn from their past mistakes, and uncover a looming menace that threatens to see you fail at any cost.

7/10 Its a good story based game about an AI with personality issues terraforming mars. The problem I have is a few of the achievements are only doable after the credits and if you save and quit the game after being asked if you want to continue once the credits are done... You can't. The game says on attempting to load the game that the save is not compatible with the games version... I just made the save 12 hours ago and there have been no updates!!! Apparently its been a day 1 issue that's now 6 years unresolved...
Not recommended Jul 14, 2026
The story and the logistics mechanics weren't really doing it for me by the time I reached the mark where I stopped playing; while the AI angle is cool from a narrative point of the view the storyline just... felt off and shallow. And the less I talk about the logistics of Per Aspera the better as it was infuriating to a certain extent which may be bad on my side for not understanding it, or it's something else entirely. Just my experience, man.
