How can we open a black door, in security room ?

[Gwido]

In the Tundra prison, I wan't to check the contraband desk, but it is located in the security room, behind a black door. And none of the two riot guards have this key. :(

Since it's not possible to dig under the security room, how can we acces to this room ? O_o

A black key? I haven't played Tundra but it seems a little odd, have you tried beating up every guard?

[Gwido]

Well, this is not a classic door, for sure. It's designed the same as colored doors, but with a black or dark blue strip.

There's the same in "Area 17", and probably in each security room.

Wait, I think it also appears in the Glorious Regime.

You need to be wearing a guard uniform

OK.
Thanks :)

In area 17, I have pierced a tunnel at the rear of the room, so I can get back my stuff even if launch the lock down. :P
