Map of E1M1
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.


This is a very simple and linear map. Walk down the path as you fight your way across the map, cross the supercharge room, until you reach a dark area. There you will find the yellow key, and behind it a switch that opens the area into the blue key. Once you have both keys, simply return to the center of the map and open the blue door. Keep going until you run into the exit.

Other points of interest[edit]


  1. Just before the first door is a section of the northern wall that lowers on pressing, revealing a shotgun and three boxes of shotgun shells. The switch inside lowers the wall again after it has raised. Both the wall and room count as separate secrets. (sector 29)
  2. See #1. (sector 30)
