The Shores of Hell

The Shores of Hell is the second episode in Doom/Ultimate Doom. All maps in this episode are credited to Sandy Petersen, though many of them were first started by Tom Hall. The episode is set on Deimos, which is being overrun and infested by the demonic forces. Levels with a mixed techbase/hell style are often called Shores of Hell style levels, in order to indicate that human technology is being gradually subverted by the powers of hell. The background consists of mountains against a red sky.

Trivia
The intermission screen changes from map to map, as long as the Tower of Babel is built.

Six buildings on Deimos are of human/UAC origin (Levels 2 through 7), versus eight on the Phobos base (all but Phobos Anomaly). Levels that feature locales of UAC origin have add-ons or repairs of hellish origin, giving the unique "Shores of Hell" style look. For example, while most buildings still use UAC keycards for locked doors, some others use skull keys. E2M3: Refinery has keycard pickups but also has skull doorframes. Some switches found in the Shores of Hell levels are UAC-style push buttons, while others are demonic heads.
