terminal 8 problem

Hi to all.

forst of all i’m sorry for the dumb question, but even looking with google i haven’t found a solution.

I have unlocked all the 7 terminals of the campaign, but at the first run I’ve missed 2 of them, so I’ve found them now, but i cannot unlock CRYIPTUM terminal, the 8th one.

does anyone know why, or someone that can give a hint??

thanks in advance
