You play as , a hacker who stumbles upon their activation key in an abandoned lab. The key is embedded with a cryptic message: "7554: The code was never the lock. It was the key to something worse."
> INPUT AUTHORIZATION CODE: 7554-GHOST-PROTOCOL
The key was delivered instantly via email. I was initially skeptical about the “verified” claim, but the code activated without any issues on the required platform (Steam). No region locks, no “already used” errors. The seller even included a short activation guide, which was helpful. If you’re worried about buying a key for this older, less common title, this verified listing is trustworthy.
