How to redeem codes
To redeem your free rewards in Once Human, there are no initial prerequisites to pass, meaning you don’t have to be a certain level or reach a specific quest to get them all:
- Once in-game, head to the Shop’s Event tab by pressing F3 on your keyboard.
- In the bottom right-hand corner of your screen, click on Redeem Code.
- Paste in the currently active code, and press ‘Redeem’.
- If it’s been successful, you’ll get an ‘OBTAINED’ screen that appears, showing everything you’ve claimed.
It’s worth remembering that codes in Once Human are case-sensitive, so be sure to copy and paste them into your game directly from our page to avoid any problems.
