Final Doom consists of two 32-level megawads (level files), TNT: Evilution by TeamTNT, and The Plutonia Experiment by the Casali brothers. TNT: Evilution features a new soundtrack, while The Plutonia Experiment uses music from Doom and Doom II. In addition to the PC version, Final Doom was also released for the PlayStation; that version included a selection of Final Doom and Master Levels for Doom II levels combined into one game.
Final Doom is a standalone game and does not require Doom II to run. The PC version is widely considered to be significantly more difficult than both Doom and Doom II.
The gameplay in the PlayStation version of Final Doom is nearly identical to that found in the PlayStation version of Doom, though it significantly toned down the overall level of difficulty from the original PC version, thus giving it a level of difficulty that is closer to that title. Many of the harder levels were removed and those that remained often had enemies taken out (most noticeably, the Cyberdemon is removed from the level 'Baron's Lair'). As in the original PlayStation version of Doom, many of the larger levels from the original PC versions of Final Doom and Master Levels for Doom II were removed, and both the Arch-vile and Spider Mastermind monsters were removed, due to technical constraints. This limited the PlayStation version to 30 levels in total. Another noticeable feature was a change in the music; the more traditional rock tracks featured in Final Doom were replaced by a creepier ambient soundtrack by Aubrey Hodges, who later composed the music for Doom 64.
There are several noticeable alterations to the presentation of Final Doom in the PlayStation version compared to the PC version. The simplistic title screens featured in the PC version have been replaced by a more elaborate title screen that features the animated flame-filled sky texture from the original PlayStation version of Doom. Many of the levels' sky textures have been replaced by different ones- some levels' skies are replaced by sky textures seen in previous Doom games, whereas others now feature a new, previously-unseen starry sky texture. Finally, due to the complexity of many of the maps featured, most of the levels are simplified, similar to many other ports of previous Doom games, and the frame rate of the game is often lower than it was in the first PlayStation Doom game. This is due to many of the original PC levels being designed as more complex than those featured in the original Doom games, because, since the original PC version of Final Doom was released several years after them, potential players of the game had generally upgraded their machines to the point that they could play such levels.
In TNT: Evilution, the UAC are once again intent on developing and experimenting with dimensional gateway technology. They set up a base on Io, one of the moons of Jupiter, with a solid detachment of space marines for protection. The marines do their job well; when the first experimental gateway is opened, they annihilate the forces of Hell. Research continues with more confidence and all security measures turned at the gateway.
A few months later, the yearly supply ship comes ahead of schedule, and looks strange and unusually big on the radar. The lax radar operators decide that there is nothing to worry about. The personnel of the base go out to behold the terrible truth: it is a spaceship from Hell, built out of steel, stone, flesh, bone and corruption. The ship's enormous gates open to unleash a rain of demons on the base. Quickly, the entire facility is overrun, and everyone is slain or zombified.
The main character, the nameless space marine (who was revealed to be the marine commander on the moon) has been away on a walk at that time and thus escapes death or zombification. After being attacked by an imp, he rushes back to the base where he sees the demonic spaceship still hovering above it and realizes what has happened. He then swears that he would avenge his slain troops and sets out to kill as many demons as possible.
In the end, the marine defeats the Icon of Sin (called by the name "demon-spitter", also known as the "Baphomet") and the game describes "something rumbles in the distance. A blue light glows within the ruined skull of the demon-spitter."
The Plutonia Experiment
In The Plutonia Experiment, after Hell's catastrophic invasion of Earth, the global governments decide to take measures against any possible future invasion, knowing that the powers of Hell still remained strong. The UAC is refounded under completely new management (the old trustees and stockholders were all dead anyway) and aims at developing tools that would prevent demonic invasions.
The scientists start working on a device known as the Quantum Accelerator that is intended to close invasion Gates and stop possible invasions. The experiments are carried out in a secret research complex, with a stationed detachment of marines. The work seems to be going well but the creatures from Outside have their attention drawn towards the new research. A Gate opens in the heart of the complex and unnatural horrors pour out. The Quantum Accelerator performs superbly: the Gate is quickly closed and the invasion is stopped. Research continues more boldly.
On the next day, a ring of 7 Gates opens and an even greater invasion begins. For one hour the Quantum Accelerators manage to close 6 of the Gates, but the Hellish army has become too numerous and too strong. The complex is overrun. Everyone is slain, or zombified. The last Gate of Hell remains open, manned and guarded by a Gatekeeper: a powerful, enormous and ancient demon that has the power to open Dimensional Gates and control or protect them.
The government, frantic that the Quantum Accelerator will be destroyed or used against humanity, orders all marines to the site at once. The player, the nameless space marine, was on leave at the beach. He was also closest to the site and gets there first. There he discovers that there is much demonic activity (howling, chanting, machine sounds) within the complex; the Gatekeeper is obviously working on something, and his work would soon reach some awful climax. He also realizes that when the marines arrive, they would not be able to penetrate the heavily infested complex, despite the firepower and support they will have. The marine decides to enter the complex and stop the Gatekeeper alone.
Work on TNT: Evilution was started by TeamTNT, a group of WAD-making hobbyists who were active on the advanced Doom editing mailing list. Just days before it was to be released as a free download online, the project was acquired by id Software, and finished in November 1995.
Brothers Dario and Milo Casali, who had contributed four levels to TNT: Evilution, were assigned the task of creating what became The Plutonia Experiment after having sent an eight-level WAD they had created to American McGee and managing to impress him along with the rest of the id Software crew. They created 16 levels each for The Plutonia Experiment in four months time, and submitted them in January 1996. Unlike their contributions to TNT: Evilution, which were edited after submission (four were also rejected due to being too large to run on the computers of the day), these were the final revisions of the levels, and Dario Casali later commented about the fact that no changes were requested, "Thank God because I was ready to throw my computer out the window at the time."
Dario Casali acknowledged the difficulty level of The Plutonia Experiment in an interview on Doomworld, stating "Plutonia was always meant for people who had finished Doom 2 on hard and were looking for a new challenge. I always played through the level I had made on hard, and if I could beat it too easily, I made it harder, so it was a challenge for me."
