The First 15 Minutes of Parasite Eve (PlayStation)

Copied from PlayStation DataCenter:

Parasite Eve is a horror action role-playing game developed by SquareSoft (now Square Enix). The game is a sequel to the novel Parasite Eve, written by Hideaki Sena. It is the first game in the Parasite Eve series.

The game begins with Aya Brea, an NYPD rookie, attending an opera with an unnamed date. During the opera, everyone in the building spontaneously combusts, except for Aya, her date, and an actress on stage named Melissa Pearce. Aya confronts Melissa backstage, and Melissa says that Aya’s mitochondria need more time to develop.

Mitochondria have taken on a new life of their own and begun to infest the city of Manhattan. It's up to NYPD detective Aya Brea to unearth the mystery behind this infestation.

Journey through the dark streets of Manhattan as you battle mutated rats and other hideous creatures on your way to Eve.

You are allowed to roam around in real-time, polygonal battle sequences. A unique option lets you customize weapons, armor and character abilities. The game is compatible with analog controllers and takes up only one block of memory for saves.
