Turrican is a 1990 video game programmed by Manfred Trenz. It was first developed for the Commodore 64 by Rainbow Arts, but 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 2, followed 1991 for the Commodore 64 and other platforms.
