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. Go straight across at the first crossroads, then take the left fork. Near the Poison sign is a secret door (marked with a misaligned texture) leading to a room with a backpack, 16 shotgun shells, two boxes of bullets, two boxes of rockets, and four medikits. (sector 36)
2. In the south of the level is a corridor with many alcoves containing imps. The north-westernmost alcove has a secret door on the back wall (marked with a Poison sign) leading to 8 shotgun shells, four health bonuses, an armor, and a medikit. (sector 153)
3. North of the alcoves mentioned in #2 is a dark area with several irregular structures. The south-easternmost one has a passage into the centre leading to two boxes of bullets, a box of shotgun shells, a soul sphere, and a light amplification visor. (sector 133)

Bugs

It is possible to get softlocked by triggering two of the collapsing tunnels near the start (two of tags 2, 3 and 4) and then triggering the third while running towards the start. A trigger (linedef 12) exists in the start that seems to be intended to prevent this cave-in by raising the east ceiling, however it is a once-only trigger that the player will have already spent by walking out of the start.

The circular nukage pool has the glowing sector effect, but is not connected to any sectors of differing light levels, making the effect useless. Because it has this effect and not a damage effect, it is also harmless to stand in.
