MelonSMP - Spooky

This mod creates a mysterious yet terrifying environment for the player.
It features these gameplay mods:

Fish's Undead Rising introduces more creatures and more loot. Future MC allows the player to attain items that are otherwise unobtainable, like bells, in a previous version of the game.

JEI or just enough items show the player blocks and crafting recipes.

Scape and Run: Parasites adds hostile parasite-themed mobs to your Minecraft game.

Spartan Shields and Spartan Weapons introduce unique weapons and shields to improve the combat experience.

Bloodmoon means that every night there is a chance of 5% (configurable) that a blood moon will rise. During the following night, monsters will spawn faster and closer to the player.

The Dr Who - Weeping Angels mod introduces statue-like creatures that slide around when the player does not look directly at them. If one of them touches the player, then they are teleported to another location.

Grue adds a hostile creature that spawns in low light levels. Macaw's Fences and Walls mod uniquely adds fences and walls.

Mutant Beasts adds mutated mobs such as creepers, that are larger and have special abilities.

Roguelike Dungeons is a mod that generates large underground dungeon structures which have a procedurally generated layout and loot.

Zombie awareness adds a multitude of zombie-related tweaks to their behaviour.

The Corpses mod creates a corpse where the player dies containing their items, this prevents these from being lost.

Good luck
