The Tomb of Terror is the third level of The Netherworld. True to its name, the level resembles a tomb and the action takes place almost entirely indoors. Many of the rooms contain deadly Lava and traps, and the dark hallways are patrolled by numerous hostile creatures.

This level brings back the Death Knight. The player must search for the Silver Key in order to proceed. The player must return to the starting room twice while travelling through this small level.
