I cannot get past the last level, it's a secret level. I'll give you a hint: Have seen those silver flying machines gathering person? Well, those machines have a purpose in the end ;)
I'll Just post 3 codes:
19-00-CE-DE-02-BF-4D-07-10-D0-21-EE-12-06-CE-52
19-10-DA-F7-07-28-0A-5A-10-30-4E-02-12-DA-77-FA
19-11-DA-F7-07-28-1A-5A-10-31-4E-02-12-DA-77-FA
The last code is 100% game completion.
Has anyone found what is CODEX entry #56?
I liked the game 5/5 Let's wait for the sequel
