Parasite Eve is a survival horror role-playing video game for the Sony PlayStation 1, developed and published by Square (now Square Enix) in 1998. Set in New York City, it follows NYPD officer Aya Brea over six days as she investigates and battles an outbreak caused by mitochondria that spur evolution in humans, culminating in the appearance of monstrous creatures. The game uniquely blends horror elements with an RPG combat system, incorporating real-time battles and traditional RPG stats, making it a pioneer in the cinematic RPG genre.
