Choose Your Own Nightmare: How I Became a Freak is a game in the series of Multipath Movies. These games are pure interactive movies that display a movie that allows for the player to select among multiple paths at opportune junctures of the storyline. In that way, the game is a "choose your own adventure" movie. This title is based on the Choose Your Own Nightmare series of horror gamebooks for kids. Tim Merrick wakes up one day and looks in the mirror to see a "horrible, twisted mess of gnarled monster flesh". The player's choices will determine whether Tim will figure out what happened to him and why, and hopefully allow him to reverse the condition.
