No monsters mode

No monsters mode is a mode that excludes monsters when playing Doom, Doom II, Final Doom and other Doom-based games. It is enabled by using the "-nomonsters" command line parameter.

Bugs


Several bugs are present with no monsters mode. On some levels, monsters are a necessity for exiting the level, such as the Commander Keens on MAP32: Grosse (Doom II). Also, the Icon of Sin's monster spawner is ignored by the -nomonsters command line argument. (When such a level is completed, each kill aside from Romero's head adds 100% to the kill percentage.) These bugs are even present in modern-day source ports.
