Again, it's the Revenant from Doom. I designed it to be more 'fresh' looking than the Revenant in the games, hence why it's cradling its guts inside its hips. It doesn't really make sense that it's just the intestines and legs that are still decaying... but, hey, it's spooky.
Very spooky indeed! I always hated the Revenant, they always kill the crap out of me when I had to fight one. Can't wait for DooM4 to come though, if it even does come out.
