Walkthrough

Map of Corrupt Outpost

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. In the dark maze near the west side, go to the chaingun, then head north to a new compartment and use the east wall. Here you will find a soul sphere, a computer area map, and one of the switches that leads to the secret exit. (sector 161)
2. In the large area at the north end, head south to a medikit and a box of shotgun shells. Open the east wall to find one of the switches to unlock the secret exit. This switch will be open if you used the one in Secret #1 as well as one in the southwest cargo room (hidden in the southeast corner where a green armor is). (sector 168)
3. Descend the steps east of the start and open a wall to the south to find one of the switches that leads to the secret exit. This switch will be unlocked upon using the one in Secret #2. (sector 183)
4. In the T-shaped intersection at the west side of the map, unlock the bars to the backpack to the east and get it. Use the north wall and flip the switch, then head to the north end of the "T" to find a teleporter. This will take you to a soul sphere, a plasma gun, and energy cell packs. (sector 251)
