Evaluation
Per Aspera launched on December 3, 2020 and received a series of content expansions over the following years: the free Green Mars DLC (October 21, 2021), the Buildings Paint Pack (July 20, 2021), the paid Blue Mars DLC (May 2, 2022), and finally the free Home DLC (January 23, 2023). Home was described as a fourth DLC adding new missions, systems, and buildings, and all seven listed DLC items are now released with no unreleased entries remaining.
On December 4, 2024 — the game's 4th anniversary — the developer posted a [development_status] update explicitly stating they are "hard at work on new games" and expressed that Per Aspera and its community have been "a defining part of our careers," framing the post as a fond farewell reflection on the game's journey. This is the clearest signal that active content development for Per Aspera has concluded, with the studio's focus having shifted to new projects.
Since that anniversary post, the team has continued to release maintenance and quality-of-life patches — including a hyperloop bugfix and QoL update in May 2026 and a modding datamodel update in May 2026 — but these are polish and community support updates, not new content. No new DLC or expansions have been announced. The combination of the developer's own words about moving on to new games, the completion of all announced DLC, and the shift to maintenance-only updates points clearly to Per Aspera being content-complete as of January 23, 2023, when the final "Home" DLC shipped.

About this 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.
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.
