Level 3: Ground Floor
Here's
the entrance hallway of the WAR building. You entered from the sewer connected
to it, and so the front door is still locked. You have to find the switch
and then get out there.
Outside,
you must search for this switch, which is crucial in getting the blue key.
In this picture you can also see a later area of the level.
Beware
of taking the green key... a band of monsters led by a Hell Knight will
teleport in to block your escape path (the way you came in).
This
level ends when you press the elevator switch. Consequently, you start
in the same elevator in level 4... only, on a different floor.
