How to redeem codes

To redeem a code in Operation One, click the cogwheel settings button in the top-right corner of the screen, type your code into the text box using the xxxx-xxxx-xxxx format, and click Redeem Code. The system is fully built into the game but no codes have been released as of April 2026 while it remains in early access.

Once the code system activates, expected rewards include cosmetic weapon skins, Credits (the anticipated in-game shop currency), and possibly operator cosmetics tied to development milestones. The developer has signaled that codes will arrive alongside a future major milestone or version launch.

The Colorful Squares Discord server and official Roblox group page will be the primary announcement channels when the first codes drop - given how quickly this game moves, setting up notifications now is worth the effort.
