Perfect Dark is out (again)

[Darunia]

Is there one cheese in every level? I only recall having found one, in the second level, but I never went in search of them, either. I recall thinking to myself, ... "is that a piece of cheese...?" which is, of course, what one would expect a person to think, in finding a piece of cheese in such an environment. If I'm not mistaken, I think it was beneath the floor, resting on a big pipe.
