Sony PlayStation



The Sony PlayStation version of Doom was a conversion of Doom and Doom II by Williams Entertainment. It was released on November 16, 1995 and ran with a modified version of the Doom engine used in the Atari Jaguar port. Final Doom's PlayStation version was also released by the same team in late 1996.

Multiplayer was unusual in that splitscreen was unavailable; two consoles had to be linked together instead. This made the multiplayer truer to the original, but it was done at the sacrifice of accessibility. Presumably two players (or more) running on one console would reduce the speed of the game dramatically.

The Final Doom conversion onto PlayStation used the same engine and team who brought Doom and Doom II onto PlayStation. It was released in October of 1996. It included a mixture of 30 levels from Master Levels for Doom II, TNT: Evilution, and The Plutonia Experiment. The instruction booklet, however, erroneously states within that the game contains 30+ levels. Although the box does not mention the Master Levels, the back cover of the instructions indeed acknowledges their inclusion. It also has support for the PlayStation Mouse which the former did not.

John Romero is quoted on the back cover, calling this the "best DOOM yet" and is credited as "Creator of DOOM".

Gameplay
The game has enhancements, updates to the graphics engine, including higher color depth, alpha blending and colorized sectors.

It contains extensive changes to the map geometry, mainly for performance reasons. Most notable is that a room is kept with a small usage of textures. Maps with large vertical distances also suffer modification. There is a noticeable slowdown in some Final Doom levels, particularly when using the highest difficulty settings.

The game uses a significantly less amount of enemies, especially the Cyberdemon and the Spiderdemon, which appear less frequently in order to achieve a much more imponent look (a counter-part to the PC versions where they are used in map tricks). There is no Arch-vile (because he had twice as many animation frames as the other monsters, and the developers "just couldn't do him justice" on the PSX) and the Icon of Sin is not in the game (instead, the final level "Redemption Denied" contains multiple Barons of Hell and one or two Spider Masterminds depending on the skill level).

However, the game includes all enemies, weapons and items of Doom II in early Ultimate Doom levels, including the first episode. Added was a type of Spectre, the Nightmare Spectre. The regular Spectre looks like a partially invisible Demon, whereas the Nightmare Spectre is dark green and tougher.

Differences between PlayStation and PC version

 * Largely pre-recorded ambient background music for all levels using a simplistic form of wave sequencing, rather than wavetable/MIDI generated audio. Aubrey Hodges created the music and reused certain songs (the symphonic rock/metal theme, most noticeably) in Doom 64.
 * The sound effects are different to the PC version, and were reused in Doom 64. Said sound effects also have echoed effects in closed-off parts of the levels (any area with a ceiling).
 * To optimize the game for the Playstation, some map areas were simplified and some textures were reduced in size. Also, some animations had frames cut.
 * No Arch-vile and Icon of Sin enemies.
 * Different status bar. The one used in this game has a darker tone (more black rather than gray in the original) and does not feature the listing of the remaining ammo of all types on the right side like the original.
 * An added status bar face gib animation.
 * The Super Shotgun has a "sleeker" appearance.
 * The I'm too young to die skill level is renamed I am a wimp.
 * There is no Nightmare! skill level.
 * There are fewer computer screens.
 * Different cheat codes.
 * Passwords are used for loading; while they store numbers as map level, skill level, health, armor and ammo, the numbers for the latter three tend to be rounded. No Memory Card usage.
 * Health and armor bonuses are worth 2% instead of 1%.

Bugs

 * A rocket launcher blast originating from a player's rocket launcher shot does not do any damage to him/herself whenever he/she is facing a corner where the walls are aligned in an angle of 90 degrees. The player must also be facing slightly off the corner's edge and be as close to it as possible. A series of images demonstrating the phenomenon in the Final Doom level Crater can be viewed here: [1] [2] [3] [4]

Inaccessible secrets in Final Doom for PlayStation
All other secrets are fully accessible.
 * In Level 9, Nessus, there is a walkthroughable (transparent thickness) wall, with a Revenant behind it (on the harder difficult levels: may be a different enemy on lower levels). On this ledge -- which is above the corridor containing the four teleport pads -- there is a megasphere and, around the corner, the BFG9000.  Many cannot get onto this ledge, but, for those that do, the BFG9000 in the top right-hand corner can (with difficulty) be taken, but because you cannot physically enter the area it resides in, the game never reports you as having found that secret.
 * In Level 29, The Death Domain, there is a switch missing which prevents the player from being able to access an area on the west side of the map.
