Final Doom

Final Doom is a first-person shooter video game developed by TeamTNT, and Dario and Milo Casali, and was released by id Software and distributed by GT Interactive Software in 1996. It was released for MS-DOS and Macintosh computers, as well as for the PlayStation, although the latter featured a selection of levels from Final Doom and from Master Levels for Doom II.

Final Doom consists of two 32-level episodes (or megawads), TNT: Evilution and The Plutonia Experiment. Unlike TNT: Evilution, which was officially licensed, The Plutonia Experiment was made by request of the team at id Software. The story in both episodes take place after the events of Doom II. TNT: Evilution features a new soundtrack not found in Doom and Doom II. Final Doom plays identically to Doom II: Hell on Earth, and even features the same weapons, items, and monsters. The original game is widely considered to be significantly more difficult than its predecessors 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, and, in addition, it was compatible with the PlayStation Mouse. Compared to the MS-DOS original, the PlayStation version's overall difficulty was significantly reduced. Many of the harder levels were removed and those that remained often had enemies taken out (most noticeably the Cyberdemon being removed from the level 'Baron's Lair'). As in the original PlayStation version of Doom, many of the larger levels from the original MS-DOS 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. 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 in 1997.

There are several noticeable alterations to the presentation of Final Doom in the PlayStation version compared to the computer versions. The simplistic title screens featured in the computer versions have been replaced by a more elaborate title screen that features the animated flame-filled sky texture from the original PlayStation version of Doom. Many of the levels' sky textures have been replaced by different ones; some levels' skies are replaced by sky textures seen in previous Doom games, whereas others now feature a new starry sky texture. Finally, most of the level layouts are simplified, similar to previous Doom console ports, and the frame rate of the game is often lower than it was in the first PlayStation Doom game.
