Fusion Piece codes give direct progression rewards, including Beli, Gems, EXP, Reroll Essence, and in one case Dungeon Tickets. You can launch the game from its Roblox experience page and redeem the codes from the in-game settings menu.

How to redeem Fusion Piece codes
Step 1: Open Fusion Piece in Roblox and enter a server. Wait until your character loads fully so the left-side menu appears.
Step 2: Open the settings menu. On most layouts, this is the cogwheel button, and some interfaces show a red square button first before the gear icon.
Step 3: Scroll down until you reach the code entry field. The box is labeled Enter Code in the Code Redemption area.
Step 4: Enter one code exactly as written, including capital letters and the exclamation mark where used. Then press Redeem.
Step 5: Check for the success confirmation. When the code works, the game shows a redemption success message and applies the rewards to your account immediately.
What Fusion Piece codes give you
These codes are built around progression items that matter early and mid-game. Beli covers purchases, Gems support summons and other reward systems, and EXP helps you move through levels faster.
Reroll Essence is tied to build changes, so it has direct value if you want to adjust abilities rather than stay locked into your current setup. LIMITEDEVENT! also includes Dungeon Tickets, which makes it the broadest reward bundle in the current set.
Where new Fusion Piece codes usually appear
New codes are typically tied to updates, events, milestone rewards, or compensation after downtime. Fusion Piece does not have a fixed public release schedule for codes, so the practical pattern is to watch for them around major game changes.
The main places tied to the game are the Fusion Piece Discord and The Horizonrise Roblox group. When a fresh code is added, it usually follows one of those update windows rather than a recurring calendar.
Use the active codes while they are still valid, since code rotations in Roblox games can change quickly after updates.
