Game Overview
A freezing underground laboratory becomes a maze of broken memories, abandoned experiments, and dread in Parasite, a first-person psychological horror adventure from MadFrogGames. You awaken as Simon Brown, a parasite specialist employed by the controversial DELTA Laboratories, with no memory of why you are imprisoned beneath the facility or what happened to its staff. The company’s history of medical breakthroughs and accusations of illegal animal testing gives every silent corridor a disturbing context. Its mood leans heavily into isolation: dim rooms, oppressive darkness, and the constant suspicion that the building is far less empty than it first appears.
Progress revolves around navigating the laboratory, following environmental signs, and piecing together clues that explain Simon’s identity and the disaster unfolding around him. Darkness is not merely scenery; moving through unlit areas is necessary to uncover routes, answers, and the tools required to escape, while also making each decision feel risky. Rather than focusing on loud action, the game builds tension through uncertainty, disorientation, and the vulnerability of being trapped in a hostile research complex. Progression is tied to discovery, with the central mystery gradually revealing why Simon is there and what DELTA has been hiding.
The strongest element is its focused, single-location premise, which turns a pharmaceutical lab into an unsettling puzzle box filled with implied biological horror. Parasite favors atmosphere and story-driven scares over elaborate systems, making it a better fit for players who enjoy slow-burn indie horror than those looking for combat-heavy survival action. Fans of first-person laboratory nightmares in the vein of Amnesia or Outlast may appreciate its familiar ingredients, though its emphasis rests on memory loss and conspiracy rather than chase sequences alone. Newcomers to horror can enjoy its direct objective of finding a way out, while genre veterans will get the most from scrutinizing the environment for hints behind its grim experiment.
