Wipe away all the mutilated limbs and buckets of blood, and Brutal Doom has a lot more to offer.
Firing a BFG blast into a horde of Imps triggers an explosion of blood that makes Johnny Depp's death scene in A Nightmare on Elm Street look tame.
Trailers announcing new versions of the mod, first published in 2010, drive this impression home.
You'd be forgiven for playing Brutal Doom for the first time and coming away with the impression that you just played the most gratuitous, over-the-top violent video game ever made.
