>>100839874my favorite and most vivid one was a squat humanoid demon (it was trying to use an enchanted stone table to birth more demons). I was in a small squad of marines trying to stop it. When we were trying to sneak past, crawling on a balcony it somehow heard us and it's torso split in half. Then it sprouted a bunch of thick rubbery loops that were about a half a foot thick, like dozens of them coming out of what remained of his hips. These loops flailed around blindly, slapping against the balcony we were crawling along, so some of them could stretch out 20 feet, so it didn't have a consistent mass/size. So these tendrils are slapping all around us and the other marines tell me to go as they shoot down at it, but the bullets just bounced right off it's snake like skin. I go to whatever goal it was they told me to, which turned out to be a level. I pull it and look down as another stone slab moves over the birthing table. Another demon was forming from it, still stone but emurging, as this other stone scraped across, covering it, it started to crush this demon. This is when I heard a sound that doesn't really exist, it was screaming so hard it was screwing up my perception, I guess if I could say it in a story it would be like a psychic scream.
Another one was when this monster was breaking into my reality, first all I saw was sawblades (sometimes a rotating blade, sometimes a reciprocating blade) suddenly appear out of nowhere and cut reality, folding it into itself. As it kept doing this I got glances at it. It was a squid but only one giant eye and it's tentacles were the saw blades.
