Jack: Haitoku no Megami

Jack Martin is a private detective. Long time ago, a terrible accident has left deep scars on his psyche, and he tries to atone for what he has done. On board of the space shuttle Gold Mary, Jack joins an organization that fights interstellar terrorism, employing people with psychic abilities. Soon thereafter, the captain of the shuttle is found murdered. Have terrorists infiltrated the shuttle, or is one of Jack's comrades a double agent? Jack must solve the mystery, at the same time discovering his own special abilities... whatever they might be.

Jack: Haitoku no Megami consists mainly of still pictures accompanied by text. The interaction is very sparse, and is confined to periodical decision-making. The choices the player makes do not influence the story line much, which remains mostly linear. However, certain scenes become unlocked depending on the decisions the player has made.

The game has scenes with nudity and explicit sexual situations.
