E2M3: The Lost Labs is the third map in episode The Road to Eternity of 2002 A Doom Odyssey. It was designed by Rory Habich and uses the music track "". In the 10th anniversary edition only a few very minor geometry changes were made that aren't visible in the map, and the things distribution remained the same.

Other points of interest[edit]


  1. Open the northernmost yellow door to reach a small intersection. Press on the slimy wall to the north to find a partial invisibility. (sector 273)
  2. Open the yellow door closest to the starting point once you have the key, then head right at the T-intersection (north) until you see a rocket. Open the wall to the left of that rocket (west) to find a passage leading to a BFG9000 and energy cell packs. (sector 309)
  3. The room on the west side of the map has damaging floor, but it holds a few switches and monsters. Flip the switch at the west end of the room, then battle your way until you can get out (step into the red circle to open the door out). Exit the hall with radiation suits, then go north and right at the fork (east), opening the yellow door. A new room ahead should be open. Inside, you can find a berserk pack, a megaarmor, and medikits. (sector 337)
  4. In the hallway where the exit door is, shoot at the button to the south to open an eastern passage in the hallway from before. Inside is a soul sphere. (sector 317)
