PAY CLOSE ATTENTION TO SIGNAGE
In the sewer levels there are signs that read...
DANGER
Why are you people so stupid? We have to put signs all over the place because if we don't you would walk off a cliff into a lava pit or something. What is up with that? Come to think of it, you won't read this sign anyway. So what's the point.
In the Citadel lever there are funny little subtitles beneath the signs on all the military buildings. I won't spoil the surprise so you will have to look for yourselves. Easy to find though.
