On level R (the lowest floor) of System Shock 1, there's a surgery machine clearly visible near the anti-radiation chamber. It's blocked only by a force door, as seen on the screenshot below.
I have no idea how to unlock that room and my guides couldn't help me out either this time. I'm pretty sure I completed everything else on this level, so it can't be a room that is relevant for proceeding with the story in any way.
Any ideas how to get in there?
