Turrican is a 1990 video game programmed and designed by Manfred Trenz. It was developed for the Commodore 64 by Rainbow Arts, and was ported to other systems later. In addition to concept design and character creation, Trenz personally programmed Turrican on the Commodore 64. A sequel, Turrican II: The Final Fight, followed in 1991 for the Commodore 64 and other platforms.
Turrican can be described as a cross between Metroid and Psycho-Nics Oscar. While the huge levels and the morph-ball function were inspired by Metroid, the overall graphics design and weapons were inspired by Psycho-Nics Oscar. Unlike many other action games of its time, Turrican did not force the player to complete a linear level. Instead, the player can explore each level and uncover secrets.
