Final Doom is a compilation of two standalone episodes: TNT: Evilution and The Plutonia Experiment, which include full sets of new levels (both of them use the same level structure as Doom II with 30 regular levels and 2 secret levels), new graphics and textures, and new text interlude screens in addition to most of the resources from Doom II and some from Doom.
Far from earth, the UAC recommenced their experiments on on of the moons of Jupiter. A spaceship, mistaken for a supply vexxel on radar, hovered above the base. Hideous demons poured out, blanketing the base with death. All your comrades were quickly slaughtered or zombified. This time, it's not about survival. It's about revenge.
