Sega Saturn

The Sega Saturn version of Doom was published in North America and Europe by GT Interactive in February 1997. This version was a port of the PlayStation version and was developed by Rage Software. As such, it features both Ultimate Doom and Doom II with the extra levels and sound design of the PlayStation version.

It was widely noted for being a rushed port with a very inconsistent frame rate depending on how much on-screen movement is present (e.g. in larger rooms, or with many monsters on screen, the game will become choppy, and in smaller, tighter rooms with only one or so monsters present, the game's speed will be much faster) and lacked several features from the PlayStation version. This affects the game's controls, as the marine's reaction time is lessened when the game is slower (it will take longer for a controller command to register). The conversion removed all of the colored lighting and echoed sound effects as well, and the sound effects are at a slightly slower and lower register. In addition, the animated fire sky that was featured in some levels was replaced with the cityscape that was featured in levels 10-20 of the PC version of Doom II, even in stages taking place in Hell. The status bar received another redesign, which is still fairly similar to the PlayStation iteration. In an interesting twist, the various monsters throughout the game move and attack slower than other ports, and the player can attack faster, especially during bouts of in-game slowdown. The end-of-game Cast of Characters sequence only runs through the monsters once before skipping back to the title screen. Many of the ambient music tracks were removed as well, causing them to repeat more often as the player progressed through the levels. Also, the fireball burst sound effect is not present, and is instead replaced with the rocket explosion sound. And although available in the European version, the Deathmatch and Cooperative multiplayer modes were not present at all in the North American version.

The information on the back of the box also contained numerous errors. The game promises "60 levels of brutal, bloody, pulse-pounding action", when 59 are actually present: The European release amends this sentence to say "over 55 levels...". Both the European and North American versions had screenshots that were taken from the PC version of Final Doom. In addition, both releases stated the game supported 2 players via linkup; however this feature was missing from the North American version and only present in the European version. The box for the European version however incorrectly states the game is 1 player only.

In July 1997, the game was released in Japan. This build was a little more optimized than the previous North American and European releases and hence was a little bit faster, though still slower than the Sony PlayStation version. It also features the multiplayer from the European version. Some of the music tracks were also switched in this release to closer match the track order of the PlayStation version.

It was distributed in Japan by Softbank Corp under publishing license from Midway (because of former Williams Entertainment PlayStation conversion rights) and GT Interactive.
