The Callisto Protocol Account
You receive login credentials to an account that already owns this game. The game is not added to your own library and the account may have usage conditions (e.g. offline mode). If you want a key to redeem on your own account, pick a non-account edition instead.
- You receive login credentials, not a key you own — sign in to the game's launcher with them to play.
- Do not change the password or email; doing so can lock you out permanently.
- The account may be reclaimed or banned by the platform, and some titles are offline-only.
- Region doesn’t apply — an account activation works anywhere.
- No refund once the login has been revealed.
Can be activated in United States
