About Poseidon

From Hangar

Shipwrecked and stranded underwater. Breathe, build, and survive in a fully aquatic island world.

🌊 Poseidon

Poseidon is an immersive underwater survival experience for Minecraft. Stranded after a mysterious shipwreck, you awaken with the uncanny ability to breathe underwater—but there's a catch. Like a shark, you must keep moving to survive.

Welcome to a world where the ocean is both your sanctuary and your greatest threat. From deep-sea ruins to glowing coral cities, Poseidon challenges you to survive, build, and explore in a realm where the sea is your only constant—until you dare to set foot on the dreaded, burning land above.

🐚 Features

  • 🧭 Survival Reimagined: Keep moving to stay alive. Stillness invites danger.
  • 🏰 Underwater Realm Building: Construct coral-covered castles and aquatic cities in the deep.
  • ⚔️ Challenging Encounters: Face relentless drowned, sea monsters, and secrets buried beneath.
  • 🌋 The Water-Filled Nether: Discover a submerged version of the underworld.
  • 📖 Lore-Driven Challenges: Complete multi-level quests and unlock mysterious books that expand Poseidon's world.
  • 🏝️ Custom Starter Islands: Choose your beginning—simple shipwreck, small monument, or a grand coral-laced domain.

🔧 Setup Instructions

> Recommended: Install alongside the BentoBox Challenges Addon for full Poseidon functionality.

  1. Download and install the Poseidon addon.
  2. Place it in your /plugins/BentoBox/addons/ folder.
  3. Start your server – new worlds for Poseidon will be generated automatically.
  4. Let pre-generation run. It only works when no players are online. The more chunks that are pre-generated, the better the performance.
  5. Log in and configure challenges:
  • Use /padmin challenges
  • Click the 🕸️ web icon to download the Poseidon Challenges
  1. Choose a starting island:
  • Shipwreck with coral
  • Shipwreck with a small monument
  • Shipwreck with both small and large monuments
  • Customize islands using /padmin bp
  1. (Optional) Tweak config.yml or use the admin settings GUI.
  • Major changes may require deleting the database and resetting worlds.

Game command

The default game command is /poseidon or /po for short. The admin command is /padmin.

⚠️ Notes

  • The End world is currently underdeveloped.
  • Lag may occur if islands are not pre-generated. Allow pre-gen to complete before inviting players.
