Inferno

Inferno is the third episode in Doom/Ultimate Doom. All of the levels in this episode are credited to Sandy Petersen, though Tom Hall originally began two of them. This episode is set in Hell, possibly the inner region of Hell. The episode is apparently named after Inferno, part of Dante Alighieri's Divine Comedy. Most of these levels have a main, center room that can be easily identified, usually circular or square in shape.
