Here are the full Grand Piece Online (GPO) controls for PC — how to run, roll, climb, block, use Haki and fight. GPO doesn’t show its controls in-game clearly, so this is the complete key list you need to get moving. Note that GPO is PC-only and can’t be played with an Xbox or console controller.
Grand Piece Online is a One Piece-inspired Roblox game by Grand Quest Games where you sail the seas, hunt Devil Fruits, fight bosses and build crews. Knowing the controls is the first step to surviving the Grand Line.

How to unlock Haki in GPO
Two of the controls above only work once you’ve unlocked Haki:
- Busoshoku (Armament) Haki — reward for completing Ray’s level 80 quest on Kori Island.
- Observation Haki — found in a small hut to the right of the Golden City in the Land of the Sky, as a reward for Rogson’s level 165 quest.
Can you play GPO on Xbox or console?
No. Grand Piece Online is only playable on PC (and Roblox mobile). There is no Xbox or PlayStation controller support, so the controls above are the only ones available.
