Straightforward mod. Compared to H-Doom, this one doesn't tone down the violence so much, which is good. But the graphical style doesn't fit Doom as much, so you might not want to play this with the standard game, if that bothers you. Freedoom fits reasonably well, but I'm sure there are better WADs to go with this mod or even mods to add to this.
Corpses have more variety, than before. As far as I can tell, there are two different poses for most enemies and you can see them from 8 different angles, instead of just one. Nice.
Gameplay remains unchanged, so expect to mow down huge numbers of women. The new sounds really add to that experience.
