Thalion Software was a German video game developer and publisher formed by members of the Atari ST demoscene in October 1988, in Gütersloh, Germany. The main aim of Thalion Software was to produce cutting edge technology games. Despite the technical quality, sales of the games never really matched expectations and by the end of 1994 the developers had left and the company eventually closed. The two founders were Erik Simon and Holger Flöttmann. Flöttmann later went on to found another video games company, Ascaron.
