Spoiler:I've ripped this thing directly from the cover, polished and modified it a little bit and made a set of sprites for a sort of a blaster weapon. Uses standard Doom palette. Credits go to DMA Design and Psygnosis Limited.
I would be glad if someone made use of these sprites.
P.S. I've never played this game and I'm not sure if I will... It's a kind of an FPS/RPG with a cooperative mode for 2-4 players (a single player mode is also available, but you have to control 4 characters directly (from a first-person view) which probably makes the game difficult).
