Overview
The ''Doom'' video games consist of first-person shooters in which the player controls an unnamed space marine commonly referred to as ''
Doomguy'', in the 2016 series, the protagonist is called the "Doom Slayer" or just "Slayer" in later entries. The player battles the forces of

. The games are usually set within sprawling bases on Mars or its moons, while some parts occur in Hell. The classic series had only a minimal focus on the narrative, much of which was in the manuals rather than the games.
More recent titles, notably the 2016 series, would feature a heavier focus on narrative.
The original game featured eight weapons, designed so that no weapon became obsolete after the acquisition of another. With the player carrying all these weapons at once, the strategy of "gun juggling"—rapidly switching between the weapons depending on circumstance—can be employed. Outside of combat mechanics, ''Doom'' levels often feature mazes, colored key cards and hidden areas. As the genre was in its infancy in the early 1990s, the player could not jump or look up and down in the classic series due to technical limitations. Some limited platforming was however present, as players could sprint at gaps and let their momentum carry them to a destination. These features were added in newer titles, with the 2016 series in particular featuring a strong focus on platforming.

''
Doom II: Hell on Earth'' was released in 1994 in a commercial format. Only minor changes were made at a technical level; the game featured new enemies, a new "Super Shotgun" weapon, and more complex levels. The game was followed by an expansion in 1995, titled ''
Master Levels for Doom II'', which added 20 additional levels. A fourth episode was added to the original game by the 1995 re-release.
From 1995 id Software were focused on the development of the new
''Quake'' series, which would be developed by the company throughout the late 1990s.
Two additional games would be released over the following years, largely created by third-party developers under id's supervision. The first of these was ''
Final Doom'', which featured 64 levels based on the ''Doom II'' engine, organised into two episodes. ''TNT: Evilution'' was developed by the modding group
TeamTNT and completed in November 1995, while the second episode ''The Plutonia Experiment'' was developed by TNT's Dario and Milo Casali and completed in January 1996.

developed ''
Doom 64'' under id supervision for release in 1997. The title featured a new engine, with larger sprites and higher quality textures. The technical changes allowed for greater flexibility with the level design, such as the ability to adjust the geometry of the map during play. The classic metal soundtrack was replaced for a more ambient and eerie soundtrack, creating a unique atmosphere that would inspire future entries. Id did not allow the title to be called ''Doom 3'', as the name was being reserved for a potential return to the franchise after the development of ''Quake''.
''Doom 3'' and cancelled fourth game (2000–2013)
The troubled development of ''Quake'' had resulted in major staffing changes at id by 2000, with a number of key figures from the development of ''Doom'' having departed. This included the original designer John Romero, who was fired in 1996.
In the interim, the company had hired former ''Doom'' modder
Tim Willits.
By 2000 a new non-''Doom'' game was being designed, but id staff had a "lack of enthusiasm" for the project, and strongly desired to remake the original ''Doom'' instead. John Carmack, among others, announced internally that they were working on a ''Doom'' game- and would continue to do so unless the company fired them. While Paul Steed was indeed fired, work on the game did continue.
The title was unveiled later that year as ''

engine, numerous technical improvements were made over the classic series, allowing greater realism and interactivity. The game used voice acting and featured a greater focus on narrative than earlier titles. A demo of the game was shown at E3 2002 and was subsequently leaked online, well ahead of the 2004 release date. At the time, it was the first ''Doom'' title in seven years, and helped renew interest in the franchise. An expansion, ''

Bethesda marketing vice president Pete Hines stated in retrospect that "it wasn't ''Doom'' enough". After ''Rage'' was not as successful as hoped, publisher ZeniMax requested a reboot of ''Doom 4'' and moved the ''Rage'' staff over to the new project. This version was built using ''Rage''s code base and suffered from disputes among staff, particularly among managers of the two projects. The game was cancelled in 2013.

re-release of ''Doom II'' featured a new expansion entitled ''No Rest for the Living'', which was developed by Nerve Software. This was structured in a similar manner to classic ''Doom'' chapters, with eight primary levels and one secret level. This release was packaged with the ''BFG Edition'' of ''Doom 3'' in 2012.
Revival series (2013–present)
After the 2013 scrapping of the ''Doom 4'' project, Willits stated that the next game in the ''Doom'' series was still the team's focus.
Hugo Martin was hired as creative director that year and would go on to be a key figure in the revived franchise. The game was announced simply as ''
Doom'' in 2014. It was released to generally positive reception in 2016, with a glory kill mechanic and additional platforming manoeuvres among the main gameplay additions. The game's multiplayer mode received three small downloadable content releases over the course of the first year, and all three were then released for free with the 6.66 update on July 19, 2017.
The 2016 series was not originally described as a continuation or origin story of earlier games, however plot details in the sequel ''
Doom Eternal'' and commentary from Martin would later describe it as a continuation of the classic series.
The 2020 re-release of ''Doom 64'' included an expansion entitled ''
The Lost Levels'', intended "to connect 'old' Doom to 'new' Doom".
A VR spinoff entitled ''Doom VFR'' was released in 2017 to generally positive reception, with reviewers discussing the movement controls in particular- which were well made albeit hidden behind menus. The game features a single-player campaign, and reused enemies and other assets from the 2016 game. The game would be the last ''Doom'' title under Willits' leadership, ahead of his departure in 2019. 2018 marked the 25th anniversary of the franchise, and saw the Doom Slayer included as a playable character in id Software's ''
Quake Champions''. That year, John Romero announced ''
Sigil'', an unofficial "fifth episode" of the original 1993 game. The episode was released for free via Romero's website in 2019, with a paid version available that included a soundtrack by guitarist

. While ''Sigil'' was developed independently, Bethesda added the episode to the console ports of ''Doom'' as a free patch in October, alongside the two chapters of ''Final Doom''.
The next main entry in the franchise, ''Doom Eternal'', was directed by Hugo Martin and released in 2020. The title sold very well, generating $450 million in revenue over the first year; double the launch revenue of the previous title. Some commentators cited the timing of the release, which coincided with a
wave of interest in gaming worldwide amid restrictions on social gathering during the

Like its predecessor, Id Software made the chapter freely available through the add-ons menu of the console ports of ''Doom'' and ''Doom II''. A spin-off for mobile platforms Android and iOS, ''
Mighty Doom'', was developed by
Alpha Dog Games and released in March 2023. Microsoft announced that it was shutting down Alpha Dog in May 2024; this resulted in the discontinuation of ''Mighty Doom'' in August.

released ''Doom + Doom II'', a "definitive rerelease" of all the pre''-Doom 64'' games alongside ''Sigil'' and a new 2 episode expansion pack called ''Legacy of Rust''. The release features new enemies and weapons.
In March 2021, Hugo Martin discussed some directions future ''Doom'' titles could take, discussing time travel or a game set in the time span between ''Doom 64'' and ''Doom'' (2016), when the Doom Slayer "first came to that place with the Sentinels, almost like a more medieval setting".
An internal ZeniMax presentation, dated to 2020 and released as part of the ''
FTC v. Microsoft'' case in 2023, indicated that a game entitled ''Doom: Year Zero'' was in development at that time, with a projected release in FY2023.
DLC for the title was also marked for 2023 and 2024. The document was produced prior to
Microsoft's acquisition of ZeniMax in 2021, but the game remained in production and was revealed at the
2024 Xbox Games Showcase as ''
Doom: The Dark Ages''.
