⚠️ Low Beta Version

The goal of this project is to create a large One Piece-inspired RPG experience in Minecraft with combat systems, Devil Fruits, factions, exploration, ships, world events, and a complete pirate progression system.

In the future, pirates will have the ultimate goal of finding the legendary One Piece and becoming Pirate King. The One Piece in this mod may not be fully canon and can have its own interpretation to better fit gameplay and progression.

Planned features include:

  • Canon-inspired attacks and abilities
  • Fighting styles and Haki
  • Devil Fruits with strengths and weaknesses
  • Crews, factions, Marines, and reputation systems
  • Islands, kingdoms, and world structures 
  • Ships and exploration systems
  • Story progression and endgame content

Get ready.
Your adventure on the Grand Line is about to begin.
