To be fair, the pixel stuff is pretty hardcore. If you overkill people, their intestines spill out stuff. If you go into any goblin camps, you can see people skewered from ass-to-mouth on pikes or being cooked over a fire. There are bloated drowned bodies in the Deep One caves. Abomination hives look like a scene straight out of Alien and their lore is straight up bodyhorror. If that's not gore, I don't know what is.
As for the actual art, you could take a look through the Pictures folder if you want. There's not a whole lot, but I think AbomCorpse1 and 2, OrcHappy, Orkind_expending, and Miscarriage_low count.
