About this project
What does online horror adventure add?
👁️ Online Horror
Survive the internet's most infamous horror legends in Minecraft.
Online Horror is a horror-themed mod for Minecraft Forge 1.20.1 that adds a dangerous new biome, terrifying boss fights, creepy creatures, unique crafting materials, and several items inspired by online horror stories.
This mod is designed to make exploration much more dangerous. The new biome is filled with strange creatures, unsettling scenery, and powerful enemies that can quickly end your adventure if you are not prepared.
🌑 New Horror Biome
A brand-new Online Horror Biome has been added to the world.
Inside this biome you'll find:
Broken phones scattered throughout the ground.
Torn notes.
Dark horror-themed terrain.
Crow feathers.
New crafting materials.
Hostile creatures that naturally spawn throughout the biome.
The biome is intended to feel mysterious and dangerous from the moment you enter it.
😈 New Bosses
Momo
One of the main bosses added by the mod.
Extremely powerful.
Can defeat unprepared players very quickly.
Drops a special note when defeated.
Designed as a difficult late-game challenge.
Blue Whale
The second major boss.
Very high health.
Strong attacks.
Drops its own collectible note.
Another difficult encounter that requires good equipment.
Both bosses are connected to the theme of internet horror legends and are meant to provide challenging boss fights rather than ordinary mobs.
🐦 New Creatures
Creepy Watcher Bird
The Watcher Bird patrols the biome looking for players.
Naturally spawns in groups.
Attacks nearby players.
Drops Crow Feathers when defeated.
Whale Lice
Whale Lice also inhabit the biome.
Although smaller than the bosses, they make exploring much more dangerous by attacking players that wander too close.
⚒️ New Items
The mod adds several new items including:
Crow Feathers
Torn Notes
Broken Phones
Redstone Sword
Special boss drops
New crafting materials
📱 Crafting
Players can craft a Broken Phone by combining:
Online Horror Dirt
Water Bucket
The Broken Phone can then be used in additional crafting recipes.
The mod also includes the Redstone Sword, which uses a unique crafting recipe based around Redstone Dust and Glass Blocks.
⚔️ Survival Challenge
This mod is designed for players who enjoy difficult survival gameplay.
The Online Horror biome is not meant to be explored early in the game. Players should gather armor, weapons, food, and supplies before entering, as many of the creatures can quickly overwhelm unprepared players.
✅ Features
New Online Horror biome.
Two challenging boss mobs.
Creepy Watcher Birds.
Whale Lice.
New crafting materials.
New weapons.
Boss drops.
Custom items.
Horror-themed exploration.
Forge 1.20.1 support.
If you're looking for a Minecraft mod that combines exploration, horror, boss battles, and creepy internet-inspired legends into one survival experience, Online Horror is made for you.
