Scud: The Disposable Assassin is a Sega Saturn video game based on the comic book series of the same name. It was released on February 28, 1997 in North America only, though it is region-free. It is unusual in that it can be played as a run and gun game, or with a light gun. The main characters and plotline are mostly the same from the comic series.
The storyline revolves around Scud, a Heart Breaker Series 1373 model assassin, a fictional type of robotic assassin, his partner, Drywall, a bizarre character whose body can hold an unlimited amount of storage space, Sussuido, a bounty hunter that at first tries to kill Scud, and several other characters from the series.
