Several months have passed since the protagonist of this game experienced the sexual pleasures and horrors of the mysterious mansion. One day he goes on a date with a girl named Reiko, and his girlfriend Yōko gets jealous. Returning home, the young man begins to think of his behavior and how to improve it, and gradually sinks into a dream that takes him back to the mansion and back to sex.
The third installment of the Twilight Zone series is very similar to its predecessor visually and gameplay-wise. Like the previous game, it is a pseudo-3D first-person dungeon crawler with turn-based battles against naked girls, where RPG activities are replaced by sexual positions and alike. New in this iteration is an automap feature and a point-and-click interface for the basic battle command, allowing the player to choose a girl’s body part to touch.
