20th December 2024: We added new Once Human codes.

Starry Studio’s sci-fi survival game, Once Human, has launched on Steam for free, and for those of you who love lining your pockets with even more freebies, you’re in luck. Codes are available for Once Human that will net you all manner of useful resources, or even skins.

Dished out on Twitter and via streams from content creators and the developer, Once Human codes can bag you items like in-game currency such as Energy Links and Activators that’ll heal you, amongst other items. Without further ado, here are all of the latest Once Human codes, and how to redeem them.
