Released in 1998 by SquareSoft (now Square Enix), Parasite Eve is a captivating blend of survival horror, RPG, and science fiction, set against the gritty backdrop of New York City during the holidays. The story follows rookie NYPD officer Aya Brea, who unexpectedly becomes the only line of defense between humanity and a terrifying bio-horror unleashed by a mysterious woman named Eve. Parasite Eve explores complex themes, fusing cutting-edge science with a chilling tale of genetic mutation, which makes for a story that remains unique even decades later.
The Story: Mitochondria and Mutation Unleashed
The plot of Parasite Eve revolves around a pseudoscientific concept involving mitochondria—organelles inside human cells that generate energy and, according to this story, have the potential for their own consciousness. Eve, the primary antagonist, is a mitochondrial entity that gains sentience and awakens after a series of horrific events, including spontaneous human combustion. Through Aya Brea’s journey, players experience the horror of encountering mutated creatures, monstrous bosses, and twisted revelations as Eve plans to evolve humanity through grotesque transformations. The detailed storytelling, based on Hideaki Sena’s novel of the same name, sets Parasite Eve apart, grounding its fantastical horror with just enough scientific theory to make it unsettlingly plausible.

Unique Gameplay Mechanics: The RPG-Horror Crossover
Unlike traditional survival horror games of the time, Parasite Eve introduced RPG elements into its gameplay. Aya’s abilities and weapons can be upgraded, allowing players to manage stats and equipment as they would in a typical RPG. However, combat is far from conventional. The game introduces a unique active-time battle system, where Aya can move around the screen to dodge enemy attacks in real-time while waiting for her attack gauge to fill up. This blend of action and turn-based combat, combined with a claustrophobic atmosphere and limited resources, gives players an intense and strategic experience rarely seen in horror games.
Additionally, Parasite Eve features the use of “Parasite Energy” as Aya’s form of magic, drawing on a mysterious connection she shares with Eve. The player can choose different abilities in combat, such as healing, enhancing her physical attributes, or inflicting damage on enemies. Balancing these powers adds a layer of strategy to encounters, especially when facing some of the game’s challenging bosses.

Atmosphere and Visuals: A Dark, Gritty New York City
SquareSoft’s work on Parasite Eve brought to life a version of New York City that felt both expansive and intimate. The environments—landmarks like Carnegie Hall, Central Park, and the Museum of Natural History—are detailed and moody, amplifying the eerie, apocalyptic tone of the game. Each setting, from the dimly lit alleys to haunting hospital rooms, serves as a reminder of the thin line between survival and destruction. Cinematic cutscenes, especially for the time, set a new standard in visual storytelling within games, making use of pre-rendered backgrounds and CGI that contribute to its atmosphere of fear and suspense.
