how did it get an AO rating?

Can anyone tell me how to get it? I think it has to do with the first game "R.I.P". There is also a lockbox there I cannot open, above it it says : "The code is dead". Thanks in advance.

i would like to have it here, there's a chance?

Can someone tell me how to unlock this achievement?

every time i go into the vents near the electrical box it causes my player to get stuck and i cant get out of it
