Map of Dr. Chaos Strikes Back

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. The small gap between the starting boat and the dock counts as a secret, however it is impossible to enter. (sector 429)
2. The sunken boat east of the start also counts as a secret, but it is impossible to get due to you being unable to enter the water from there. (sector 435)
3. In the building southwest of the start, go to the torch and lower the shelf where it is to access a basement area with Gauntlets of the Necromancer and mace spheres. (sector 454)
4. In the bedroom with the silver shield and possibly a firemace, use the decorative torch and the fireplace will open, revealing a Tome of Power. (sector 445)
5. In the green key building, head to the high ledge on the east end and shoot east through the fence to a switch. This will lower a wall near the switch with a Morph Ovum and a quiver of ethereal arrows. (sector 93)
6. In the building southeast of the start, head east of the intersection and then north. In this room, open the south wall to find a Bag of Holding. (sector 618)
7. In the building with the blue key, use the north wall on the structure south of the key, then head east, northeast, and open the south door. On the sarcophagus, pick up the phoenix rod. (sector 798)
