Stranger Realms - Upside Down

by tastybento · on Modrinth

The familiar world is shadowed by a terrifying, inverted dimension - the Upside Down. A dark survival challenge inspired by Stranger Things.

Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

🔮 Stranger Realms — The Upside Down Awaits

The familiar world is shadowed by a terrifying, inverted dimension — the Upside Down.

Stranger Realms is a unique BentoBox game mode inspired by the concept of parallel dark dimensions. Your players inhabit a normal island, but beneath it (or alongside it) lurks a twisted mirror world filled with danger, darkness, and mystery.

🎮 How It Works

🌍 Two dimensions — a normal island and its dark mirror counterpart
🌑 The Upside Down — an inverted, hostile version of your island
⚔️ Survive both — resources and challenges span both dimensions
🔮 Cross between worlds — portals connect the normal and dark realms
👥 Multiplayer — teams face the darkness together

⚙️ Features

Unique dual-world concept — nothing else like it in the BentoBox ecosystem
Atmospheric gameplay — darkness, danger, and exploration
Full team system — protection, roles, and permissions
All BentoBox addons compatible
Free and open source

📦 Installation

Requires BentoBox on a Paper server.

Install BentoBox
Place StrangerRealms.jar into plugins/BentoBox/addons/
