The GoW-style Blood Spatter mod is designed to give you the identical blood spatter that is found in Gears of War, and since Doom does a similar thing when you get hit, the developer figured he'd
take the ball that ID dropped and run with it. So, after a bit of tweaking and fiddling, the result is ready for you to download! Unfortunately, there is no spatter from you shooting or chainsawing enemies at close range; TheRealSceneGraphManager also stated that the imp getting shotgunned was thrown in because it looked really badass, not because it demonstrated how you can get blood n' guts on your face in close quarters.
