Yes, it's not a first person shooter, but with how suicidally difficult it is, it might as well be compared to Doom on Nightmare mode, and that's just on normal difficulty. I can't explain how many times I've replayed fighting the Butcher in this mod alone, but it's more than I planned to do. Still I highly recommend because of the additional characters, updated graphics, extra spells and weapons, new missions, and all the other awesome stuff.
