About the Game

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.

I was writing a positive review but the more I wrote the more I dislike the game. Only buy if you ignore there is a campaign and find it on sale there is no difficulty in this game, and there really isn't any decision

Per Aspera, the game where solar panels (starter power gen) have no day/night cycle and wind farms (first researched power gen) have day/night cycles.. Imagine thinking you can research better power generation? Couldn't

The logistics system in a game is so frustrating that made me give up at phase 3 of terraforming. Over and over again, you see items being brought from across the planet even though there are items available right next

Slow, slow and even more slow. The game's pace is so slow that you can literally fall asleep watching it play. After a while the water starts rising and rising destroying your buildings again and again and again. This

Love seeing the planet change green! A chill game with story choices. Wish the building limit were higher and there was an option to not zoom in on new launches. Also, the initial stages of increasing oxygen took

11.1 hours, 0/55 achievements, because I've been min/maxxing what for other players is the first 10 minutes for 3 hours, then fell asleep. 10/10 at least the beginning, it's all I've seen.
