Walkthrough

Map of Eraser

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

Secrets

1. You need to find four switches to access this secret at the northwest end, indicated by four orange lights. One switch is located in the room northeast of where the secret is. One of them is in the water maze at the northeast end (at the south side). A third is located in a winding path northeast of the blue clearance. The final switch requires some extra work, starting at the southeast side of the main complex. In the library here, a hidden skull eye is on the shelf above the seats. After using it, leave this area to the west, then north and enter the big halls northeast of this room. There will be a new button to the south before the next turn, which lowers the lift here. Take it up and open the door, then go south and flip the switch. This also lowers a teleporter back to the location of the secret, and if you flipped the other three switches, the four orange lights will be lit up and you can now get the plasma magnum. (sector 53)
2. In the water maze at the northeast end, head to the east side and find a wall with several slits on it. Head west of it and use the button on the computer which opens the aforementioned wall. This wall contains a computer area map. (sector 1020)
3. In the room south of the blue clearance room, raise the east lift, ride up, and enter the south area. Flip the switch, shoot the switch behind you, and deal with the enemies from the side compartments. Return north and look at the north wall, finding one that has a green slimefall. Use it, then face west and shoot the red button in the distance. Return south and enter the southwest compartment to find two 10 gauge shells, a rocket, a nanokit, and a plasma cell. (sector 1855)
4. At the east side, in the room with the largest set of steps, head west, north to the bars, then west again. Enter the southwest room with all the monitors and use the westernmost one with a candle in front of it. After using it, head back east to the bars, then south and slightly southwest to get to a teleporter to a secret temple section. (sector 4046)
5. In the maze at the west end of the main area, open the bright room at the north end and lower the lift here. Ride up and head north past the Khu Node #1 sign to get a nanokit, a plasma cell, and a single mag. (sector 4425)
6. In a room at the east side with a single teleporter, open a vent at the southeast wall to find a hidden maze section. (sector 4664)
7. In the gold clearance area, climb the steps at the southwest end near a lift, then jump south. Use the west wall and take the teleporter. This separate area has its secret sector in the exit at the west side. (sector 5569)
