I had never played any real-time "3D" type games on the Amiga (it wasn't until Doom that these arrived) - the only other game I'd played like this prior to it was Sultan's Maze on the Amstrad CPC. There was Dungeon Master et al, but that wasn't full real-time movement. This was also my one of very first proper FPS games. Sure the graphics weren't great, but the game played brilliantly. Me and a work colleague spent hours playing it through during quiet periods. It introduced a new genre to me and showed that the future of gaming was going to get even more interesting.
