never released and only some enemy sprite designs have surfaced. Super Turrican (NES) Released for the NES, this Turrican game was created by Manfred Trenz alone. It is based roughly on the levels of the first two Turrican games. Super Turrican and Super Turrican 2 (SNES) The Super Turrican games were developed for the SNES by Factor 5. They were released in 1993 and 1995, respectively. Unreleased games Turrican 3D was intended to introduce 3D graphics in the Turrican series, but was not released because publisher THQ stopped development. The game was intended for PC (Windows) and Dreamcast. Screenshots and videos show how the world of Turrican would have looked. In an interview, Manfred Trenz, creator of Turrican, Turrican II, Super Turrican (NES) and co-developer of Turrican 3D, stated that many members of the project were far too profit-oriented, and the project failed as a result. Thornado is another never-released Turrican spin-off. Handled by the US branch of Factor 5, they did not use the name Turrican because of legal issues. It was developed first for the Nintendo 64 and later for the GameCube. All that is available from this game is a piece of preliminary music composed by Chris Huelsbeck and some art assets that were reused in Star Wars: Rebel Strike, such as the Golden Gate-looking bridge. The "Thornado Demo" track which was released as a teaser for the then-upcoming GameCube game, was in fact running on the older Nintendo 64 sound hardware using Factor 5's new proprietary MusyX software sound engine. The Thornado demo, although not available on Factor 5's website anymore, can still be found on Chris Huelsbeck's page at GarageBand.com. Next-gen Turrican in April 2007, a Gamasutra article revealed that Factor 5 was working on concepts for a new Turrican game.

Since the game was being planned once again by the US branch of Factor 5 and they went bankrupt not long after, this game was not released.
