A series of game books based on classic horror stories. In them the player can be either the monster or his nemeses. Two were published in one the player is either Dracula or Jonathan Harker in the other he is either Victor Frankenstein or the creature. They were written by J. H. Brennan and published by Harper Collins.
In both book players had 100 life points and 5 stats (determined by the roll of a d6). These were Speed and Courage (to hit), Strength and Skill (damage) and finally Psi.
Due to the fact that the books contained two games in one, each paragraph was split into two sections: an action and a location. The main choices and events of the story were found in the action section whilst descriptions were found in the location section.
