$29.99Per Aspera Terraform Mars, uncover its past
You are AMI, the AI in charge of turning Mars green, and in Sandbox Mode up to three co-op friends can join you. Together you place mines, factories and colonies across the whole planet, balance resources and research, and watch oceans and air slowly build. Slow strategy, shared control, one very large red garden.

Terraforming Mars with up to four minds
Co-op lives in Sandbox Mode, for up to four players. You share the same planet and the same to-do list: lay down outposts, connect mines to factories to colonies, research new tech, and push temperature, water and air toward human-friendly.
There is no lobby round or match timer here. One of you expands the power grid while another fixes a resource bottleneck, a third starts a terraforming project, and the fourth zooms out to admire the slow spread of blue. It suits co-op friends who like talking through plans rather than shouting callouts.
A slow planetary construction set
This is base building at planet scale, built from NASA geography and real-world science ideas. You manage around ten raw and refined resources, place worker hubs, storage and transport routes, and pick branches from research trees to shape your approach.
Expect watching and waiting between decisions while drones haul goods and the atmosphere ticks upward. The story campaign, with its voice cast and choices about colonists and a threat on Mars, stays single-player, so bring co-op friends for the sandbox: building, optimizing and terraforming together.
Good to know about co-op?
How does co-op work in Per Aspera?
Up to four players terraform together in Sandbox Mode. You share one Mars, building structures, managing resources and guiding the planet toward habitability as a group.
Can you play the story together?
No. The narrative campaign, where you play AMI and make planet-wide decisions, is single-player. Co-op friends join you for open-ended sandbox terraforming instead.
What will you actually do together?
Place and connect buildings across Mars, keep power, materials and colonies running, research technologies, and run terraforming projects that change water, air and temperature. Coordination is the game: who expands, who fixes shortages, who plans next.
Is it fast and competitive?
No. There is no PvP here, only shared building against the demands of a barren planet. Sessions are slow real-time strategy and management, best for co-op friends who like talking, delegating and watching a plan come together.
