Ultimate Doom (PlayStation Doom)

Ultimate Doom is the first episode of the Sony PlayStation and Sega Saturn versions of Doom. It contains 33 levels in total. Of these, 24 are taken from the Atari Jaguar version of Doom and retain the simplifications originally made for that platform. Another six are original PC levels which did not occur in previous ports with revisions applied by Williams Entertainment. The remaining three are exclusive levels created by Williams.

The episode shares the same story with the individual episodes of The Ultimate Doom, but combines the four original episodes&mdash;Knee-Deep in the Dead, The Shores of Hell, Inferno, and Thy Flesh Consumed&mdash;into one continuous episode with no text messages except at the end.

A major change is that enemies from Doom II appear in many levels, especially on the Ultra-Violence skill level. Megaspheres and a super shotgun can also be found in some of the exclusive levels.
