In Brutal Doom Platinum 3.0 (yeah, I think that's the updated version so far) it's not a Demolisher though but it has new attacks. It can attack while climbing on ceiling and then return to floor, causes bumping which also deals huge damage everything around it. The spreading bombs are also very deadly like sometimes they can be found at ground like mines, if you accidentally step on them you blow up yourself. Quite a deadly guy in higher difficulties! I had a hard time beating it on my No Rest For The Living playthroughs (watch here: https://youtu.be/gJ-WLmdzHCs). I can't imagine fighting it on a tight spaces but I think in Doom E3M8 it will be good fight.
