Walkthrough

 * Letters in italics refer to marked spots on the map. Sector numbers in boldface are secrets which count toward the end-of-level tally.

Essentials
Go around the cacodemon cage (to the right is best) and go through the western doorway on the south wall. You will come to a nukage room. Run straight though, heading south, to find a shotgun on a round pedestal with scrolling sides.

Turn right (west) into a green marble hall. Take the first right and then the first left to come to a metal door. Go through the metal door to find the blue keycard.

Return to the round pedestal with scrolling sides and head east into a roundish room with a nukage pool in the center. There are two semi-hidden doors in this room; they are off-texture portions of the wall, bordered by brown metal. If you are playing with an OpenGL port, a slime trail is also visible if you look at the walls closely. The door on the northern wall opens from the other side only. Click the door on the eastern wall and go through (this is secret #2).

Continue eastward as far as you can and turn left. Look for the blue door ahead on your right.

Go through the blue door and follow the passageways. Eventually, you will come to a dark room with many pillars. Zig-zag your way west and north until you come to a platform overlooking another nukage room.

Run straight through the nukage room, heading north. Follow the passageways to the exit.

Other points of interest
You may wish to visit the area behind the big metal door (just ahead on your right) to acquire powerups or to kill monsters. But then come back out into the hallway near the start.

Secrets

 * 1) From the round pedestal with scrolling sides, head west into a green marble hall. Go through the doorway on the south side of the western wall. Continue straight through and drop into a pool of blood. Exit through the passageway to the north and go up the stairs to find a plasma rifle.
