Go through the door in front of you then turn right to find a button, which will open a closet containing a shotgun (plus an imp on Ultra-Violence (UV) and Nightmare (NM) skill levels). Head north into a passage containing zombiemen and turn right then left, then go straight ahead at the next junction to find some steps leading into a room with barrels and tech pillars. Turn right to find some health bonuses then enter the next chamber and kill the zombiemen and shotgun guys then flip the switch to lower a blue lift. Ride the lift up and cross the gray bridge in front of you, then turn right to find a chamber containing the blue keycard.

Go back to where you found the health bonuses and continue north through a blue key door, then walk up the steps to a hallway with rectangular lights - as you walk over the first light, watch out for a closet with imps opening on your left. Step on the blue teleporter at the end of the hallway, kill the demons in front of you on Hurt Me Plenty (HMP) skill level or higher, then go round the corner and push past some more demons and imps to a switch that will lower the floor beneath you. Once you reach ground level, head south until you reach the helipad then east through an open gate which leads to a brick passage. Follow the passage until you reach a UAC door (which does not open) then continue east past some shotgun guys until you see a demon rise from beneath the floor. Open the silver door on your right and follow the path south past more zombiemen to a room with a shotgun, then go through the door next to the exit sign. There is a small shuttle in the final room - flip the switch to open the shuttle door then press the computer terminal inside the shuttle to finish the level.

Other points of interest[edit]

Finding secret #2 or #3 will allow you to finish the level without collecting the blue key. A skull switch placed behind the blue key door allows it to be opened without that key.


  1. Exit the starting room and head north to a fork. Head east, then north. Use the light on the east wall to get a megaarmor, or an armor on UV and NM. (sector 33)
  2. Exit the starting room and head north to a T-junction. Head west, and in this room, press on the small recess on the right wall. After doing this, return to the junction and head all the way east, then east into a new hall which contains a cacodemon (or baron of Hell on UV and NM) and a teleporter. The teleporter takes you to a rock south-west of the helipad, containing a plasma gun and an energy cell pack. (sector 208)
  3. On the bridge leading to the blue key, hop into the nukage north of the bridge, then use the switch in the passage. After riding the lift, get on the next step and use the north wall to find a hidden switch. Use it, then run up the steps going south and into an open door before it closes. In this room, hop into the hole to pick up a berserk pack as well as a shortcut to the exit. (sector 284)
  4. In the hallway east of the helipad, find the UAC door at the south-west end of the hall and attempt to open it. Although it will not open, another door does open. Head east in the hall and quickly enter the room just to the north to find a backpack. (sector 149)
  5. Head onto the tracks past the exit and you will eventually find a supercharge. (sector 173)
