If such a level is not available, the player will be warped to MAP01: this effect is created by the secret level information not having been initialized. If the player uses a secret exit outside of MAP15 or MAP31, the next level will be the one that was last entered via an intermission screen.

Depending on the specific episode and level this occurs on, the player may end up either skipping several maps, repeating the level they just left, or being sent back to an earlier level.įor example, MOUNTAIN.WAD reaches E3M9 from E3M5, and continues on to E3M7, skipping E3M6 entirely.

However, upon completing it, the player will be taken to the level immediately following the one they were meant to access it from. If the player activates a secret exit elsewhere than in one of the four aforementioned levels, the player will go to the secret level as usual. The actions of the secret level linedef types have been hard-coded into the engine. E4M9: Fear, accessed from E4M2: Perfect Hatred.
