Ah, yes Doom.
Have you tried making explosive blood? You really have to be an elite player to get anywhere with that!
Other things to try:
-Blood & bullet puffs change into health potions & armor helmets. (make sure the change is instant, so the game dosen't crash)
-Fist of BFG bLast

-Negative mass enemies

monsters fly towards you when you blow them away. You get a lot of gooshing guts in your face that way. hehe

-Change your pain frames to that of the archvile attacking. Then you create an archvile flame attack against whomever hurt you Last

Just don't hurt yourself with a rocket!

-Make dead bodies explode after 30 to 60 seconds. Watch your step!
