The Parasite Eve series is a cinematic role-playing franchise that blends survival horror elements with real-time combat. It debuted with Parasite Eve in 1998 and was followed by the sequel Parasite Eve II in 1999. The games follow NYPD officer Aya Brea as she battles mutated creatures created by rogue mitochondria.
Conceived as a sequel to Hideaki Sena’s Japanese sci-fi novel, the franchise represents Square's first major foray into Mature-rated software. The original
Parasite Eve (1998) combined cinematic CGI cutscenes with a unique Active Time Battle system, allowing players to move in real-time while waiting for an action gauge to fill. Its commercial success led to a
Parasite Eve [Greatest Hits] (1998) re-release.
To assist players with the intricate weapon customization and Chrysler Building bonus dungeon, specialized strategy guides like Parasite Eve [BradyGames] and Parasite Eve [EBGames BradyGames] became popular companions to the release.
The gameplay formula shifted significantly with
Parasite Eve 2 (2000), also released as
Parasite Eve II. This sequel adopted real-time combat and tank controls, moving closer to traditional survival horror design. Accompanied by the
Parasite Eve II [BradyGames] guide, the sequel expanded the lore beyond Manhattan to the American Southwest. The series remains a landmark for its distinct fusion of Japanese RPG mechanics with Western cinematic horror aesthetics.
