Psycho Chaser is a vertically-scrolling shoot 'em up that features an android protagonist who strides up the screen. It was Sting Entertainment's first video game: the developer would later be better known for their JRPGs like Baroque and Yggdra Union. The player character, the eponymous Psycho Chaser, is a sophisticated android warrior with multiple built-in weapons that was designed to combat an AI that has gone out of control. The game was a PC Engine exclusive for almost two decades until it was added to the Wii's Virtual Console in 2008. Neither version of the game was released outside of Japan.
