This modpack adds such things as the cave dweller and the knocker mods to make the world more hostile.
From creepy critters to downright bonechilling beasts you will encounter all types of scary mobs that make outlast look like a walk thorough a park! If you dare enter the mines you better be prepared to dig yourself a hole to survive the night from the most terrifying creatures just so you can build out your dream kitchen in your cozy home nestled in a pretty nook of your world so you can hide away from the horrors you choose to put yourself through!
(Please suggest any more mods you think would be a good edition for later versions!)
