Athanasia is an immersive horror FPS set in an abandoned research facility in South America overrun with prehistoric predators. You play Carmen Flores, a researcher sent to investigate reports of disappearances and strange phenomena. The developer cites System Shock and Dino Crisis as reference points, and the design follows: you are expected to outthink the animals rather than outshoot them.

Steam 250 weekly chart: #42 on the Top 50 Games of the Past Week, scored 6.92 from 39 reviews at 92% positive, released 19 October 2026. Chart position via Steam 250.

Key features

Knowledge of the enemy as a resource

You gather information about your foes and surroundings to take different approaches to encounters. Making enemy knowledge a collectable is what separates an immersive sim from a shooter: the thing that gets stronger over a playthrough is the player's understanding, not only the inventory.

Predators instead of monsters

Prehistoric animals behave like animals — they hunt, they are territorial, they are not out to get you personally. That distinction matters because an animal can be avoided, misdirected or waited out, which gives a horror FPS a non-combat solution space that a monster designed to stalk the player does not.

Hidden pathways over corridor progression

The facility is built as a winding maze with routes to be found rather than a sequence of rooms to clear. Rewarding navigation gives the player an escape valve from encounters they cannot win, which is the mechanism that keeps immersive-sim horror tense without being unfair.
