A bit help needed with Wolfenstein

[Czar]

I´m on the level where you are supposed to kill 5 ss officers and.. well.. I manage to kill them all without being undetected and I go to the spot where the level ends and I have one mission objective left, that is to not be detected. How can that be? and how can I get past that.

I'm starting up wolfenstein right now. I'll be back in a few.

Press 'N' and see which objective you haven't accomplished yet. I really don't feel like playing through the mission again, and I have an essay due in a few hours.

Remember in the wine celler when one of the guards was looking for a certain wine bottle or something? Did you kill the drunk guy? He dropped some stuff, maybe you have to get that to pass the level.
