Walkthrough[edit]
Essentials[edit]
You begin in a courtyard with an X-shaped pool. Enter the corridor east of the pool and look north to see a shotgun guy guarding a door, then go through it to enter a room with a staircase and five more doors. Collect the megaarmor at the top of the stairs, then go through the northern door on the west side to reach a bridge, then go down the stairs on the north side of the bridge to find another door. Open the door and kill any zombies waiting behind it, collect the rocket launcher then go down the steps to collect the blue skull key. Go back to the six-door room and open either door on the north side, drop into the nukage river to collect a radiation shielding suit, then follow the river north and west past some imps to a set of narrow steps. Climb the steps and open either blue door at the top to reveal a red teleporter, which will send you to the plinth with the red skull key.
Go back to the six-door room and open the eastern door to enter a room with a narrow walkway, follow it south to a supercharge then continue on to another door which leads to a long hall; do not fall in the nukage on the west side of the hall as you will not be able to escape. Go to the south end of the hall and climb down the steps here to a narrow ledge with a button, press it then go back to the red key area and open the south door to see the yellow skull key on a plinth ahead. Step through the opening in the east wall to see one of the circuit boards open and reveal a button—there are actually four buttons here, and pressing each button will reveal the next one for a few seconds. Pressing the fourth button will open a fifth button behind you, which will lower the plinth with the yellow key. If you miss the key or any of the buttons, walk through the doorway again to reveal the first button again.
Go back to the starting courtyard and open the south-western door, kill any waiting imps then shoot the switch through the southern window to lower one of the two doors blocking the exit switch. You can now open the yellow door at the north end of the room and flip the switch behind it to end the level.
Other points of interest[edit]
- Armor, a super shotgun and three sets of shotgun shells can be found in the north-east corner of the starting courtyard. Approaching the items causes three (depending on skill level) zombiemen, shotgun guys or chaingunners to teleport behind you.
- Behind the western door on the north side of the six-door room is a button. Pressing it lowers a platform to the north for a few seconds, which has a chaingun on it.
- A plasma gun is placed on a pad west of the red key. Taking the weapon may trigger a crusher trap above it; this can be avoided by approaching the plasma gun slowly so that you just touch it.
- A partial invisibility can be found in the south-east corner of the area with the red key. To get to it, enter the alcove with the three energy cells to open the back wall, then go through it to find a lift that goes up to the powerup.
Secrets[edit]
- The sector in which you begin the level is flagged as secret, and is thus impossible to miss. (sector 0)
