Evaluation
Pathologic 3: Quarantine is a free prologue to the main game, Pathologic 3, which launched on January 9, 2026. The prologue released on March 17, 2025 and served as an introduction to the full game's world and mechanics. It is no longer available for purchase on Steam — the store listing shows no purchase options. This is consistent with the prologue having fulfilled its purpose as a pre-release promotional piece once the full game shipped. The prologue itself was always described as a free standalone piece of content, not an ongoing product, and the developer's post-launch communications for the Quarantine app focused exclusively on bug fixes and polish before pivoting the team back to main game development. There is no indication of planned future content for the Quarantine prologue specifically.
Evidence
Pathologic 3 (the full game) launched on January 9, 2026, confirming the prologue's purpose as a pre-release teaser has been fulfilled.
Final patch for Quarantine addresses bug fixes and polish; developer states 'the core team is returning to development of the main game,' signaling that active work on the prologue has concluded.

About this game
Learn how the story of Pathologic 3 began with the free Quarantine prologue.
Pathologic 3: Quarantine is a narrative-driven adventure about a young scientist in search of immortality and a mysterious plague outbreak in a small town. Find out what drove a celebrated academic to leave his acclaimed lab. Examine patients, uncover strange secrets, and make first steps towards defeating Death.
Bachelor Daniil Dankovsky is a celebrated young doctor from the Capital. The Powers That Be do not appreciate his search for immortality. The rumor of an immortal man who lives in a faraway steppe town may be exactly the breakthrough he needs… if he can get to him.
Bachelor’s story is told through his subjective lens and through the lens of his persecutors. Did he really do — or fail to do — all the things he is accused of? Can he fix his own story by going back in time and making different choices? In Quarantine, watch how this non-chronological storytelling begins.
Fight the Sand Plague by examining patients and diagnosing them, but also investigating their life situations to find out the unpleasant truths they may hide. To save more lives, issue decrees based on your research. Face the horrifying personification of the Plague in the burning flesh.
Dankovsky is a sharp mind in search of the truth, willing to do anything to find it. Anything you see can tell a story and become a piece of your mental map of the world. Look at everything around you, connect the dots, and read the world!
