In the future, scientists mastered the technique of cloning, succeeding in creating fully functional artificial life forms. However, a powerful corporation took control over creation of such beings, using them for their own purposes. One of those artificial humans, a girl named Emma, managed to escape, holding some important information that supposedly incriminates the corporation. You control another artificial girl, Nel. You were just created, and the assignment you receive from your boss Elena is to find where Emma is hiding, and to prevent her from leaving the corporation building.

Savior is a Japanese-style adventure game, without puzzles or action elements. However, unlike most other hentai titles, you can freely move in a 3D environment, viewing it from third- or first-person perspective. You navigate Nel through the game world, exploring it and searching for clues. Important events are displayed either as still CG images or pre-rendered movies. Many of these images and movies contain explicit sexual content. You can view them again from a special menu accessible from the title screen.
