Doom 64 (1997)

Doom 64 is a first-person shooter game by Midway Games. It was first released for the Nintendo 64 in 1997, as the second spin-off game in the Doom series after Final Doom (1996), and the fourth game in the series overall. A remastered port was developed by Nightdive Studios and published by Bethesda Softworks for Windows, Nintendo Switch, PlayStation 4, and Xbox One in March 2020, and for Stadia in May 2020.
Doom 64 was developed from 1994 by Midway Studios San Diego under supervision of id Software, the main developer of the Doom franchise, and was tentatively titled Doom: The Absolution. It has a customized version of the Doom engine, enabling new kinds of level geometry, and dynamic colored lighting. It has new sprite graphics for weapons and monsters.
It received positive reviews from critics, praising its graphics, level design, soundtrack, and general atmosphere, with some criticizing the lack of new gameplay elements compared to the previous games of the series. It gained a cult following, with several fan-made PC source ports and mods.
== Gameplay ==
Doom 64 gameplay is similar to earlier Doom games. The player must advance through 28 story levels (and 4 secret levels) by battling demons, collecting weapons and keys, and activating switches to reach the level's exit while surviving deadly ambushes and traps. The Doom engine and gameplay elements were customized, and all visual assets such as weapon and monster graphics are unique to Doom 64.
=== Weapons ===
All the weapons from Doom II are present, but with new sprites and sound effects. The chainsaw has two blades instead of one, the fists have bloodstained gloves instead of brass knuckles, the plasma gun has an electric core that emits a sparking sound, the rocket launcher has a small kickback, the shotgun's priming handle is at the grip instead of under the barrel, and the double-barreled "Super" shotgun reloads faster and causes kickback.
A new weapon named the Unmaker which is a hit scan weapon, but looks like a projectile weapon uses the same cell ammunition as the plasma gun and BFG 9000. It had originated in the Doom Bible in 1992, and was planned for the original Doom in 1993, but never appeared. Its appearance in Doom 64 is its only official appearance prior to Doom Eternal, in which it is spelled "Unmaykr". With the power of three ancient artifacts found throughout the game, it becomes more powerful by shooting three laser beams (at a quicker rate than default) instead of one. The first artifact increases the laser speed, the second artifact adds a second laser, and the third artifact allows the weapon to fire three simultaneous lasers which can automatically aim separately from one another, allowing the weapon to attack three different enemies at once with huge amounts of rapid damage.
== Plot ==
Following the Doom Marine's success at thwarting Hell in Doom, Doom II: Hell on Earth, and in the Final Doom storyline, a planetary policy is established to quarantine the U.A.C. research installations with apocalyptic levels of radiation. For years, the installations stood motionless and abandoned, until a long-forgotten satellite monitoring one of the installations, barely functioning due to years of being subjected to high levels of radiation, sends a message back to Earth.
The message indicates that a single entity, with vast rejuvenation powers and masked by the extreme radiation levels, escaped detection in its crippled state. This entity systematically altered decaying dead carnage back into corrupted living tissue, resurrecting the demons.
As the only experienced survivor of the Doom episodes, the Marine is sent in alone to exterminate them. Later, he realizes the demons had planned for this, after he unknowingly allowed himself to be lured back into Hell. The demons are unable to defeat him, and with the Unmaker, he eventually battles and kills the Mother Demon. The game ends with the Marine, no longer capable of having a normal life following his encounters with Hell's forces, deciding to remain in Hell forever to ensure no demon ever rises again.
In the Lost Levels from the 2020 remaster, the story continues as the Mother Demon was revealed to have a sister called the "Resurrector". It banishes the Marine back onto Phobos, forcing him to fight his way back to Hell to stop the Demons. It branches the storyline between the original games with the 2016 reboot of Doom and Doom Eternal.
== Development ==
Doom 64 was developed by Midway Games at its San Diego studio. id Software, the primary developer of the Doom franchise, supervised the project. Development began in late 1994. Its tentative title of The Absolution was changed to Doom 64 for brand recognition, and reused as the name of the last level.[citation needed] Midway wanted to include every demon from the original games, and a few extra levels, into the final product, but deadlines and storage size constraints of the Nintendo 64 Game Pak cartridges made them exclude the levels and a few demons.[citation needed] Midway stated that a multiplayer mode was not included because Nintendo did not provide the necessary resources for multiplayer programming. Midway justified the decision based on alleged slowdown during split-screen multiplayer in other games on the console and the competitive nature of the mode. A Midway representative stated, "Everyone knows that the best part of playing multiplayer is not knowing where your opponent is and with a four-player split-screen, everyone can easily see where their opponents are."
The environments were built from 3-dimensional polygon models, and the enemies were created by pre-rendering sprites with SGI workstations. The Nightmare Imp was originally developed for the PlayStation version of Doom and appeared in a near-complete beta of the game, but was removed just prior to release for unknown reasons. It debuted in Doom 64 instead.
Doom 64 was slated to be a North American launch game but was postponed until April 1997. A Next Generation writer speculated that this was due to id Software having expressed dissatisfaction with the level designs, an assertion that is not otherwise substantiated. Nintendo's then-recent decision to remove the ability to run over animals from the Nintendo 64 version of Cruis'n USA raised concerns about the possibility of censoring Doom 64, but Midway vice president of software Mike Abbot said Nintendo had not voiced any concerns about the game's violent content. He pointed out that Cruis'n USA was perceived by the public as a family game, but the Doom series was targeted towards mature gamers, making violent content less of a concern.
The music and sound effects were composed by Aubrey Hodges, who had created the original sound effects and music for the PlayStation version two years earlier. The original Doom 64 team was working on a potential sequel titled Doom Absolution designed only for two-player deathmatches soon after the first game was released, but canceled it. Because id Software was impressed with the team's work on Doom 64, they were assigned to the Nintendo 64 version of Quake at this time.
Midway Home Entertainment shipped Doom 64 on March 29, 1997, for release on April 4.
