If there's one Minecraft mod that's made to be a nightmarish Body Horror Cosmic Horror Story, this would be it.
- Several assimilated Mobs are full-on Body Horror, some like the Assimilated Bear and Assimilated Ender Dragon having mouths that split right down their neck or body. That's right, not even the Ender Dragon is safe from these things.
- Feral Mobs take the Body Horror a step further, losing their skin and growing tentacles from their mouths to the point that they barely resemble their Vanilla counterparts.
- Most Crude Mobs are made of bloody flesh and chunks, often incomplete or arranged in haphazard ways.
- The players themselves are not immune to Call of the Hive, aka the parasite infection. It's surprisingly easy to contract, such as being near infected mobs, taking damage from most parasitic mobs, being near the residue spawned from parasites or beckons, or even just being near a parasite's remains. Infected mobs will become assimilated in a matter of minutes, and while players are immune to being assimilated while alive, a slain infected player will leave an Assimilated Adventurer behind wearing their armor, minus the chestplate.
- Every time the parasites advance to the next Phase, a Scare Chord plays, which range from unsettling to horrifying, signifying to the player that their world is more and more doomed.
- Parasite Biomes. The sky within is dark and gloomy, Body Horror structures litter the area, the trees have pulsating masses, the stone and grass all infected... and it's naturally filled with several high-tier parasite mobs.
- The game is heavily skewed in the favor of the parasites, with infection of the world usually being an inevitability, not a possibility.
