Square Enix's Parasite Eve deserves a modern remake 24 years later

In October 2022, the horror gaming landscape was shifting. Konami and Capcom had both announced major plans for their classic franchises—Silent Hill and Resident Evil were getting modern remakes, getting the resources and attention that comes with being industry titans. But one publisher seemed to be sitting on the sidelines, and it shouldn't be. Square Enix had a horror game in its vault that deserved the same treatment: Parasite Eve, a 1998 title that pioneered something no other game has managed to replicate in the quarter-century since.

The game's origins trace back to an earlier Square Enix project. When Hironobu Sakaguchi was developing Final Fantasy VII, his initial concept involved a detective in New York City chasing an ecoterrorist group called Avalanche. That setting and premise never made it into the final FFVII, but Sakaguchi didn't abandon the idea. Instead, he took that New York detective story and fused it with the Japanese horror novel Parasite Eve, creating something entirely its own. The 1998 game that emerged followed Aya Brea, a rookie cop with the NYPD, as she spent six days hunting an entity named Eve—an intelligent mitochondrial being capable of possessing people and causing them to self-destruct.

What made Parasite Eve distinct was its refusal to fit neatly into existing categories. While Resident Evil and Silent Hill defined survival horror as a genre, Parasite Eve approached horror through the lens of a role-playing game. The combat system was the clearest expression of this hybrid identity. Rather than shifting to a separate battle screen like traditional JRPGs, encounters happened on the exploration map itself. Combat ran in real-time but could be paused, using the Active Time Battle system familiar from Final Fantasy games. Players controlled Aya's movement directly, dodging attacks and positioning for counterattacks, then unleashing weapons and items when her ATB gauge filled. Item scarcity added genuine tension to each encounter. The system bore a resemblance to what Square would later perfect in Vagrant Story, released two years after Parasite Eve. Nothing quite like it existed before, and nothing quite like it has existed since.

Aya herself was a remarkable character. Designed by Tetsuya Nomura and created by Sakaguchi, she felt like a synthesis of gaming's best protagonists—the determination of Leon Kennedy, the vulnerability of Claire Redfield, the complexity of Cloud Strife. She anchored a narrative that embraced mature, adult themes in ways Square Enix hadn't attempted before, making Parasite Eve the company's first M-rated game. The combination of compelling protagonist, distinctive gameplay, and darker storytelling resonated. In 1998, the same year Resident Evil 2 launched, Parasite Eve became Japan's third best-selling game. A sequel followed in 1999, and a third installment arrived in 2010. Then silence. Beyond occasional re-releases on the PlayStation Network and a Japanese-only appearance on the PlayStation Classic, the series went dormant for twelve years.

The tragedy is that nothing has successfully replicated what Parasite Eve achieved. Even its own sequels abandoned the formula, with Parasite Eve II and The 3rd Birthday attempting to chase Resident Evil's survival horror template or third-person cover-based shooting instead. In an industry where AAA remakes have become routine, where Square Enix itself demonstrated mastery of the form through the Final Fantasy VII Remake trilogy, Parasite Eve remains untouched. Some remakes feel obligatory, but the best ones—like Resident Evil 2—bring forgotten classics to modern audiences while maintaining reverence for what made the original special. Parasite Eve deserves that same care, whether as a full remake, a remaster, or, ideally, a new entry that reclaims what made the series singular. The horror landscape is crowded with sequels and revivals. There's room for something that has never been matched.
