MonstersSounds+

This pack makes monsters far more scary and intense. 

I sampled many different video games to get the right sounds for each mob, such as:

doom, Skyrim, Call of duty, Dying light, SCP secret lab, and others.

I take no credit for the sounds this is just a mash-up.

This mod works really well with the sound filters or sound physics (both client-side) mod. I would recommend using Drago’s creepy mob’s resource pack, as it makes the mob’s eyes glow. That along with the Chocapic’s shader with lots of fog will get you a great scary gameplay.

Enderman Sounds:

So many other monsters that are scary as well! Download the mods and listen to the others!

Good luck Minecrafting!
