Map of Rotten Core

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 large lava pit north of the start, there are five columns to the west. Use the middle one and take the teleporter to get a radiation suit and a soul sphere. (sector 150)
2. Enter the lava again and go to the east side, near the crushers. South of them, enter a cave with a medikit, a radiation suit, and a box of rockets. (sector 171)
3. In the second area, head to the east side and find a switch to the north end. Shoot it, then go south to get a radiation suit as well as a teleporter back. (sector 318)
4. In Secret #3, open the cracked wall to the east to get a backpack. Head south and open the other cracked wall to get the computer area map. (sector 320)
5. Go into the teleporter from Secret #5 to teleport to a megasphere. (sector 325)
