Killer Queen
Description
Killer Queen is a Japanese adult thriller kinetic novel which puts the player in the shoes of Souichi Mitsurugi, a student who wakes up one day to find that he has been locked inside an abandoned building along with twelve other people as part of a deadly game. Each player has a metal collar device fastened firmly around their necks and a PDA device which corresponds to the letter of a playing card from Ace (A) to King (K). To their horror, they realize that their PDAs also contain instructions for a different set of objectives which must be completed within 72 hours, or else the collars around their necks will explode. As no-one knows which PDAs or objectives the other contestants have, Souichi must decide who he can trust in order to beat the game and survive.
The game features voice acting for all significant characters except the protagonist and includes scenes with explicit sexual content.
