I was asking this before, but came up with the wrong results apparently. There is a game I used to play, I think it was on 8 disks, and it worked with an 68000 ECS machine and was pretty much just like DOOM. Everyone told me it was called Citadel, and that sounded right, but when I look up the game, all I can find is some Mid-Evil point and click dungeon roaming type game that is NOTHING like DOOM.
Anyone know what I am talking about? It was Sci-Fi.
