Brutal Super Secret Level refers to a trope frequently used in wads consisting in using the 32nd slot for an extremely difficult map. The level is moved to slot 32 so that players don't have to play it because in extreme cases the level proves to be extremely more challenging than the overall difficulty of the wad. . This trope very often includes highly gimmicky maps and especially slaughtermaps.
