"Parasite Eve" was SquareSoft's first M-rated game, and the first major American and Japanese game development collaboration for the company. It was produced by Hironobu Sakaguchi and directed by Takashi Tokita. Music for the title was composed by Yoko Shimomura who was widely acclaimed for her work to create an "inorganic" and "emotionless" soundtrack that saw two album releases. "Parasite Eve" received positive reviews; critics praised the graphics and gameplay, but found the overall game too linear and with little replay potential.
