E3M7: The Haunted Halls

The Haunted Halls is the seventh and Secret Level of The Netherworld. The level consists of a series of challenges for the player - either deadly traps or monster encounters. The architecture features narrow dark corridors and several larger chambers, all of which have pools of Lava in them.

This level brings back the Vore as a regular enemy. The level is rather tight and crowded, and requires the player to endure many enemies with very little room to dodge.

This level is infamous for lopsided scores in clan play. This has led to the creation of the term "rapecloset", a Deathmatch round so highly favored to one team over another, being used by the community.
