About Per Aspera

Per Aspera puts you in the mind of AMI, an artificial consciousness tasked with terraforming Mars. Using NASA geographical data and scientific theories from real space agencies, you balance resources, research technologies, and shape a planet‑wide environment for future human colonists.

The game offers a narrative‑driven campaign for solo play and a sandbox mode that supports online co‑op for up to four players. Voice talent from Troy Baker, Phil LaMarr, Laila Berzins, Yong Yea, Lynsey Murrell, and Nneka Okoye adds depth to the story.

01 / THE GUIDE

Planetary Simulation

The simulation tracks a complex well of resources that affect climate, atmosphere, and colony health across the entire Martian surface. Every structure you place contributes to the global system, requiring careful balancing.

Scientific theories from real space agencies inform the model, so conditions such as temperature, pressure, and radiation behave according to theoretical research, creating a lifelike challenge.

  • Watch how a change to one resource ripples through multiple planetary metrics.
  • Compare early‑game resource levels with later stages to see long‑term effects.

02 / THE GUIDE

Research Tree

A branching research tree lets you develop technologies rooted in real science, from atmospheric processors to habitat modules. Each branch tailors your terraforming plan and unlocks new building options.

Choosing different research paths leads to distinct planetary outcomes, encouraging experimentation while managing the same resource network.

  • Plan a research direction before allocating resources.
  • Contrast tech trees focused on atmosphere versus surface engineering.

03 / THE GUIDE

Narrative Mystery

The narrative presents difficult decisions with planet‑wide consequences. As AMI you uncover relics of past colonization attempts and confront a looming menace that threatens your mission.

Story moments challenge moral concepts and require you to defend colonies from unknown combative forces, shaping the ultimate conclusion of the campaign.

  • Listen for dialogue clues about the threatening presence.
  • Weigh long‑term planetary impact when making major choices.

04 / THE GUIDE

Sandbox Mode

Sandbox Mode removes narrative pressure, allowing unlimited time to craft the Martian landscape. It leaves you free to experiment with the planet's landscape on your own schedule.

The mode supports online co‑op for up to four players, letting groups test strategies together without a scripted storyline.

  • Use sandbox to trial risky technologies before applying them in the campaign.
  • Invite friends to compare collaborative builds versus solo experimentation.

05 / THE GUIDE

Multiplayer Co‑op

Up to four players can terraform together online in Sandbox Mode, coordinating construction responsibilities. Working together can help manage the planet‑wide systems efficiently.

Co‑op lets groups coordinate their strategies in real time while using the game's research and building tools.

  • Assign each player a distinct focus, such as resource gathering or research.
  • Communicate priorities to avoid duplicated effort.
