DOOM II secret levels: MAP15, Wolfenstein, Grosse and campaign order
Locate the original secret-level branches and understand the main campaign structure.
Edition covered
The original 1994 DOOM II: Hell on Earth PC campaign: thirty main maps and two secret maps. Publisher images show classic DOOM II. Final DOOM, Master Levels, No Rest for the Living and later DOOM + DOOM II episodes are separate content.
The campaign has thirty main maps

The normal route runs from MAP01 Entryway through MAP30 Icon of Sin. Two additional maps, MAP31 and MAP32, branch from the regular sequence rather than replacing its ending.
| Starting map | Exit choice | Destination |
|---|---|---|
| MAP15 Industrial Zone | Ordinary exit | MAP16 Suburbs |
| MAP15 Industrial Zone | Secret exit | MAP31 Wolfenstein |
| MAP31 Wolfenstein | Ordinary exit | MAP16 Suburbs |
| MAP31 Wolfenstein | Secret exit | MAP32 Grosse |
| MAP32 Grosse | Exit | MAP16 Suburbs |
Find the secret exit in MAP15
Industrial Zone contains the route to MAP31 Wolfenstein. Taking the ordinary exit continues to MAP16 Suburbs. Use a save before choosing if you want to explore both outcomes.
| Map or range | Landmark | Why it matters |
|---|---|---|
| MAP01 | Entryway | Campaign opening |
| MAP07 | Dead Simple | Arena with enemy-triggered progression |
| MAP11 | Circle of Death | End of the first broad campaign block |
| MAP15 | Industrial Zone | First secret branch |
| MAP20 | Gotcha! | Large boss-enemy encounter |
| MAP30 | Icon of Sin | Final arena and rocket-timing objective |
Find the second secret inside MAP31
Wolfenstein contains another secret exit leading to MAP32 Grosse. The ordinary exit skips Grosse and returns to the main campaign at MAP16.
Recognize expansion mapsets
Master Levels and Final DOOM use different maps, and later collections include additional episodes. This route table covers only the original Hell on Earth mapset.
