Gameplay and design
The combat system in Parasite Eve was quite distinctive for an RPG at the time. It was built on Square's signature Active Time Battle (ATB) mechanic but added real-time movement. During battles, players could directly control Aya to move around the battlefield, dodging enemy attacks while the ATB gauge gradually filled. Once the gauge was full, the game paused, allowing players to calmly choose to attack, use items, or activate abilities, with the screen showing the attack's range to help players judge if they were within effective distance. This design preserved the strategy of turn-based combat while introducing the tension of action games, making it a bold experiment during Square's exploratory period.
Beyond combat, character growth was also thoughtfully designed. Aya gained experience points by defeating enemies, and upon leveling up, she received bonus points (BP) in addition to base stat increases. These BP could be freely allocated to ATB speed, item carrying capacity, or weapon and armor attributes. Players could tailor Aya to different playstyles, such as focusing on rapid attacks, high defense, or item usage. This freedom made each level-up a decision-filled experience and gave players more personal strategies when facing different enemies.
The weapon and armor tuning system was another major feature. Throughout the game, players found various guns and armor, each with attributes like attack power, fire rate, magazine size, or defense and special resistances. By using tools and super tools, players could transfer attributes from one piece of equipment to another, even inheriting special effects. This meant players could craft their ultimate gear, such as a pistol with high fire rate and fire damage, or a coat that greatly boosted magic defense. This deep customization made the equipment system highly engaging.
The main storyline took place across multiple areas in Manhattan, where players could freely explore streets, subway stations, museums, and other locations, but enemy encounters were random. This design borrowed from traditional RPG random encounters but, combined with real-time combat, made each encounter unpredictable. The map also contained hidden supply points and story events, encouraging exploration. However, the overall progression was linear, with clear main objectives and few branches, which led some players to feel there was little replay value after completion.
After finishing the main story, the game unlocked an 'EX Game' mode. In this mode, players kept previously acquired weapons and items but reset their level, and a new 77-floor Chrysler Building was added for challenge. The enemies in the tower were stronger, and the rewards were richer, serving as the ultimate test of equipment and strategy. This mode was extra challenge content, unrelated to the main plot, more like a dessert for players who enjoyed grinding for gear and pushing their limits.
Background and release
The story of Parasite Eve is set in New York in 1997, with the protagonist being Aya Brea, a new NYPD officer. On Christmas Eve at Carnegie Hall, a performance suddenly turns into a hellscape as audience members spontaneously combust, and Aya awakens to supernatural powers in the chaos. She discovers that behind it all is a mysterious entity named Eve, who is trying to destroy humanity through human combustion. Aya must track Eve across Manhattan within five days, uncovering the connection between her own origins and the disaster.
The game is a sequel to Hideaki Sena's novel of the same name, but the plot is not a direct adaptation. The novel depicts mitochondria suddenly gaining consciousness and causing a series of eerie events, while the game moves the timeline forward, making Aya the daughter of the novel's characters Kunihiko and Mariko Anzai. This setup allows the game to continue the novel's world while forging a new storyline. For players who read the novel, many details in the game bring a knowing smile, such as Aya's mother's identity and the scientific concepts related to mitochondria.
The game's initial setting was actually Tokyo, but producer Hironobu Sakaguchi proposed changing it to New York during development. This change not only made the game more appealing to the international market but also placed the 'spontaneous combustion' events in more iconic locations like Carnegie Hall and Central Park. New York's urban atmosphere complemented the game's stark style, enhancing player immersion during exploration.
Parasite Eve was first released in Japan on March 29, 1998, and in North America on September 10 of the same year. It was Square's first game to receive an ESRB M (Mature) rating and the first title released by Square Electronic Arts, a joint venture between Square and Electronic Arts. A week before the North American release, a minor incident occurred: over 200 copies of the game were mistakenly shipped to Best Buy stores, allowing some players to get the game early, which sparked some discussion at the time.
The game's commercial performance was quite impressive. As of February 2004, it had sold 1.94 million copies worldwide, with 1.05 million in Japan and 890,000 overseas. This was a solid result for the time and laid the foundation for subsequent sequels. However, it's important to note that this figure refers only to Parasite Eve itself, not including sales of Parasite Eve II or The 3rd Birthday.
Development
The development team for Parasite Eve was quite star-studded. The producer was Hironobu Sakaguchi, Square's visionary figure, who also co-created the core concept. The director was Takashi Tokita, who had previously worked on titles like Final Fantasy IV. Both were considered 'experimentalists' within Square, willing to try new things on the mature RPG framework. The game took about two years from initial planning to completion, with the first six months spent primarily on direction and setting.
The technical foundation was a modified version of the Final Fantasy VII engine. At the time, Final Fantasy VII had just achieved great success, and its 3D engine was already mature for rendering characters and environments. The development team added real-time combat physics and movement logic to this engine while retaining the pre-rendered background visual style. This technical approach allowed the game to achieve top-tier graphics for its era, especially the character models and cutscenes, which left a strong impression on players.
The development process was an attempt at Japan-U.S. collaboration. In addition to the main team in Japan, some production work was done in the United States, including CG animation creation. American artists Steve Gray and Darnell Williams handled most of the CG work, and a team of about 30 people assisted at a studio in Hawaii. This kind of international collaboration was uncommon at the time and brought communication and workflow challenges, but the final results were quite impressive.
The creation of protagonist Aya Brea was also interesting. She was conceived by Hironobu Sakaguchi himself, with character design by Tetsuya Nomura—the artist later renowned for Final Fantasy character designs. Aya's name was taken from Sakaguchi's daughter, giving him a personal attachment to the character. In terms of design, Nomura gave her a neat short haircut and a sharp detective look, fitting her NYPD role while exuding a cool beauty, making her a hallmark of the game.
The game's music was composed by Yoko Shimomura, who created an 'inorganic' and 'emotionless' style for Parasite Eve. Shimomura stated that her inspiration came from the rhythms of American nightclubs, using electronic and ambient sounds to evoke urban coldness and mystery. The theme song 'Primal Eyes' and the ending theme 'Somnia Memorias' became classics, with the latter performed by Shani Rigsbee, featuring a long, ethereal melody. The soundtrack was released on May 21, 1998, by DigiCube, and later a remix album titled Parasite Eve Remixes was released, containing 10 remixed tracks.
Reception and legacy
Parasite Eve received generally positive reviews from media and players upon release. On Metacritic, it earned 'generally favorable' reviews, with critics praising its graphics and innovative combat system. At the time, combining real-time movement with pausable commands in an RPG was indeed eye-opening. However, several reviews noted that the linear structure limited exploration freedom and that there was little replay value after completion, criticisms that were often mentioned in later discussions.
The game also garnered awards. It received three nominations at the 1999 Interactive Achievement Awards for 'Console Game of the Year,' 'Console Action Game of the Year,' and 'Console Role-Playing Game of the Year,' and although it didn't win all, it demonstrated industry recognition. In 2000, when Japanese gaming magazine Famitsu conducted a reader poll of the top 100 PlayStation games, Parasite Eve ranked 16th, showing its standing among players.
Parasite Eve was also part of the 'J-horror' cultural phenomenon of the late 1990s. At the time, Japanese horror works like Ringu were sweeping the globe, and the game rode this wave, combining horror elements with RPGs to introduce more Western players to Japanese horror. Its unique 'mitochondrial horror' concept, blending science fiction with psychological unease, stood out as a breath of fresh air among horror games of that era.
The game's success spawned a series. In 2000, the sequel Parasite Eve II was released, further expanding the world; in 2010, the third entry, The 3rd Birthday, was released for PSP as a third-person shooter, but with significant changes to story and gameplay. Additionally, the game was adapted into a manga, expanding its influence. As of 2010, the first two games in the series had shipped over 3 million copies worldwide, demonstrating the IP's enduring appeal.
In the digital age, Parasite Eve has continued to live on. In 2010, the game was re-released in Japan via PlayStation Network, and in North America the following year; in 2018, it was included in the Japanese version of the PlayStation Classic mini console. For old players, these re-releases offer a chance to revisit a classic; for new players, they provide a convenient way to experience this experimental RPG. Although over two decades have passed, the game's status among players remains solid, marking an unmissable chapter in Square's history.
