The intermission screen with a visual presentation of all the Inferno levels.

Inferno is the third episode in Doom/The 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 named after Inferno, part of Dante Alighieri's Divine Comedy. The name of the final level is also a reference, as Dante describes Dis as a city encompassing the four lowest levels of Hell. At the end of the episode Doomguy returns to Earth through a portal possibly opened by demons using Mars technology.

Most of these levels have a main, center room that can be easily identified, usually circular or square in shape.

End of Episode Message

The loathsome Spiderdemon that masterminded the invasion of the moon bases and caused so much death has had its ass kicked for all time.

A hidden doorway opens and you enter. You've proven too tough for Hell to contain, and now Hell at last plays fair -- for you emerge from the door to see the green fields of Earth! Home at last.

You wonder what's been happening on Earth while you were battling evil unleashed. It's good that no hellspawn could have come through that door with you...
