Persona: Ingyaku no Kamen

A series of gruesome murders shocks Japan. Young women are kidnapped, tortured, and killed under mysterious circumstances...

The protagonist wakes up in what looks like a hospital, but is in fact a special psychiatric facility on a space station. The hero doesn't remember anything, not even his name. Three young women - Shelly, Elisa, and Aoka - will help him to find his memory, and he will gradually realize who he is and what is his mission.

Persona: Ingyaku no Kamen can be considered a visual novel, since the only input done by the player throughout the game is a choice which girl to visit. The rest of the game consists of dialogues and cut-scenes (many of which have sexual content). Depending on where the hero goes, and at what moment, the game takes a step towards one of the several endings, most of which are considered "bad". To facilitate the player's efforts to reach the best ending, he is given a set of statistics, which will be raised or lowered, indicating how close he is to full success.
