An unfinished CODEX crack that was not ment to be for the public. Someone (I assume one of their testers) leaked the crack to the public. Because the NFS heat crack was an unfinished one and reveals all the loopholes and exploits used to crack Denuvo, cs.rin.ru admin Christsnatcher locks the NFS Heat topic, seems to claim it was a mistake to share the latest crack and it will help Denuvo patch an exploit.
