Turrican is a 1990 video game programmed and designed 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 II, 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. The Spectrum version was voted number 36 in the Your Sinclair  Readers' Top 100 Games of All Time.

The series started in 1989 on the Commodore 64 with a demo level of  the full game which was released in 1990. Turrican became very  popular due to its high technical achievements, demonstrating  graphics which many did not believe to be possible on a C64. Turrican was developed mainly by Manfred Trenz and published  by Rainbow Arts. A later Amiga conversion was produced by  Factor 5.

Turrican was also released for the Atari ST, Amiga, CDTV,  Mega Drive/Genesis, Game Boy, PC Engine, ZX Spectrum and  Amstrad CPC. The console ports were handled by The Code Monkeys  and published by Accolade.
