What are Once Human codes used for?
Codes are extremely useful in Once Human, as they grant you free Energy Links, Activators, Adrenaline Shots, or even a new skin for your vehicles.
Energy Links are a vital resource for fast traveling, unlocking Memetics, and so much more, while Adrenaline acts as your primary healing resource when you go down. Then, Activators serve as your main healing resource and work perfectly when increasing your HP recovery.
