Another original-ish FPS game that sadly got overshadowed by the release of DOOM, this one comes from Germany, with a few voiced cutscenes (in German, despite the rest of the game being in English) between levels.
The game has several interesting features different to other Wolfenstein 3D clones at the time, including but not limited to stepping sounds depending on surfaces, elevators, security cams in black-and-white (complete with visual noise!), and slopes.
