Momentum Games is the developer of Athanasia, an immersive horror FPS set in an abandoned South American research facility overrun with prehistoric predators, published by Black Lantern Collective. It entered Early Access in October 2026 and charted at #42 on the Steam 250 weekly list with a 92% positive rating.

The studio names System Shock and Dino Crisis as its reference points, and builds Athanasia around gathering knowledge of enemies and environments so that encounters can be solved by understanding rather than firepower.
