Walkthrough

Map of E1M3

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. Lower to the northwest room and open the southeast wall with the poison sign to find a chainsaw. (sector 21)
2. Take the door west of the northwest room and open the door at the top of the steps. Head east and use the north wall to lower to a soul sphere. (sector 19)
3. In the south hall, press on the misaligned wall to the north to find armor bonuses and a shortcut back to the north room. (sector 63)
4. Shoot the red wall behind the yellow key to open a wall north of the lift. This leads to a blue bar and a plasma gun. (sector 78)
5. After you get the blue key, return to Secret #4 and open the blue bar to find a switch. This opens a wall in Secret #3 leading to the area behind the cage at the starting point. The wall closes when you enter which reveals the secret exit switch. (sector 69)

Bugs

A multiplayer-only chaingun (Thing 139), shotgun (140) and rocket launcher (141) in northern areas have no flags set for any of the three difficulty classes, so they do not actually appear in the level.
