Detalion S.C, was a Polish video game developer founded by a partnership of six people, that first met in the early 1990s (Maciej Miąsik, Robert Ożóg, Łukasz Pisarek, Krzysztof Bar, Roland Pantoła & Danuta Sienkowska), working from game developer and publisher LK Avalon. These games (particularly Mysterious Journey: Schizm) were noted for the complexity and great difficulty of their puzzles, and also were hailed as having some of the best graphics in the industry at the time. Detalion was one of the first developers to use the DVD-ROM disc as an effective medium for software distribution.
