>What mods are you using?
There are a couple of mods that I'm using, if you want to recreate your experience yourself you can do it with just some core mods, but besides that there are some that I think improve the experience a lot.
CORE MODS
>Abyssalcraft
Can't have a creepy Minecraft playthrough without some Lovecraft. This mod adds rituals, monsters, a whole new corrupted biome with dangerous monsters and interesting stuff to find, and besides giving you some endgame to look towards, it will be one of main sources of danger during daytime as the monsters do not burn in sunlight.
>Weeping Angels
Not only do those fuckers increase the tension tenfold, they are dangerous both at day and at night. Not only that but this mod has a built-in jumpscare that is going to scare you from time to time whenever one of those fuckers appears. Absolutely vital for building spooks.
>Deadly Monsters
The monsters in Minecraft were kind of creepy at the very beginning, but with time they've become less so, so you need to spice up some of the night-time monsters with some new ones. Also includes some dayling ones too, so it makes the world generally more dangerous.
>Recurrent complex/Ruins
You absolutely fucking need one or another, because it's kind of boring to explore a world where there is nothing interesting in. Also, the whole "seek shelter only for a night" is only possible with this.
Additional Spooks
>By the Gods
A side mod to Abyssalcraft allowing you to summont Azathoth and fuck up your game.
>Defiled lands
Adds YET ANOTHER Terraria-esque corrupted biome with it's own list of monsters making the world darker than it is.
>SCP: Lockdown
Mostly allows different SCPs to spawn in your gameworld for additional spooks and danger.
>Zombie Awareness
Makes the easiest and dumbest enemy in the game more dangerous, makes you leave blood trails behind that zombies smell, zombies run for cover when in sunlight, they hear sounds, spawn in bigger numbers and look after light sources.
>Thaumacraft
Adding more arcane shit into your world seems like a fun idea. Also has monsters on it's own.
>Better Animals+
Now the wildlife is after us too. Adds normal wildlife as well as some hostile animals and a creepy deer-skellington miniboss that we might find in the wild. I do not use the base mod because that would fuck with some things in abyssalcraft and ruin the tension.
Helping yourself
>Camping
If we want to play a hobo character, we need some camping and backpack mods. The Camping Mod does both at the same time.
>Flan's mod or other gun mod
If you're playing against so many threats at once, you need to bring some /k/ to have any chance of survival. I will not be using vehicles for now because that would fuck up the atmosphere, that might change in the end game though, but come on, you cannot have spooky camping without some /k/
Stuff nice to have
>Minecraft comes alive
Adds a bit to the villages and makes you care a bit more for the deaths of the people who you meet on your way without getting in the way too much.
>Portable Craft Bench
You will be moving a lot so a bit of convenience can't hurt, seeing that it's a bit annoying constantly destroying the same workbench.
New untested mods
>Harvester Night
Adds a spooky halloween-themed miniboss. Not tested yet.
