Walkthrough

Map of Caves, Rocks, and Cacos

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. After getting the blue key, jump into the blood and go through the nearby teleporter. You will be teleported to a ledge with a stimpack and a box of shotgun shells. Jump down into the blood and towards the western end of the crack in the floor. You will drop down to a long blood passage which leads, via several rockets and a rocket launcher, to a soul sphere. Note that the part that counts as a secret (just before the rockets) is very narrow, so you might not trigger the secret first time. (sector 144)
2. Directly opposite the blue door is a ledge with a plasma rifle. (sector 67)
