The ''X-COM'' core series consisted of four main games published by [[MicroProse]]: ''[[UFO: Enemy Unknown]]'' (also known as ''X-COM: UFO Defense'', PC and [[Amiga]] in 1994, [[Sony PlayStation]] in 1995), ''[[X-COM: Terror from the Deep]]'' (PC in 1995, PlayStation in 1996), ''[[X-COM: Apocalypse]]'' (PC in 1997) and ''[[X-COM: Interceptor]]'' (PC in 1998). The premise of the franchise is that an [[alien invasion]] beginning in 1999 prompts the creation of a [[Clandestine operation|clandestine]] paramilitary organization codenamed X-COM (an abbreviation of "[[Extraterrestrial life|E'''x'''traterrestrial]] '''Com'''bat") by a coalition of funding nations. The player is charged with leading this force and tasked to secretly engage and research the alien threat. The sequels, against new alien invasions, are set underwater (''Terror from the Deep'', set in 2040), in a futuristic megacity (''Apocalypse'', set in 2084), and in space (''Interceptor'', set in 2067 and making it a prequel to ''Apocalypse'').

''UFO: Enemy Unknown'', featuring a [[turn-based tactics|turn-based]] ground combat system, remains the most popular and successful game in the series, having been often featured on various lists of best video games of all time.<ref>[[UFO: Enemy Unknown#Reception]]</ref> The first sequel, ''Terror from the Deep'', was quickly created by MicroProse's internal team; based on the same game engine and used largely identical gameplay mechanics. ''Apocalypse'' took several new directions with the series, introducing an optional [[Real-time tactics|real-time]] combat system and shifting the aesthetics to a [[Retro-futurism|retro-futuristic]] style. A spin-off game, ''Interceptor'', constitutes a hybrid of a strategy game and a [[space flight simulator game|space combat flight simulator]].

After ''Interceptor'', [[Hasbro Interactive]] purchased MicroProse, acquiring its studios and the ''X-COM'' brand. There were talks of ''X-COM'' toys, comics, and even a cartoon show.<ref>{{cite web |url=http://uk.pc.gamespy.com/pc/x-com-ufo-defense/1216654p3.html |title=GameSpy: Enemy Unknown: An X-COM Retrospective - Page 3 |publisher=Uk.pc.gamespy.com |access-date=2013-08-22 |url-status=live |archive-url=https://web.archive.org/web/20131029194218/http://uk.pc.gamespy.com/pc/x-com-ufo-defense/1216654p3.html |archive-date=2013-10-29 }}</ref> A budget range, turn-based tactical  [[play-by-mail]] multiplayer game ''[[X-COM (Email games)|Em@il Games: X-COM]]'' was released in 1999. In 2001, Hasbro published ''[[X-COM: Enforcer]]'', a poorly received [[third-person shooter]] loosely based on the events of ''Enemy Unknown'', marking a low point in the series. The ''X-COM'' games were also released as part of four compilation releases: ''X-COM (Collector's Edition)'' (1998),<ref>{{cite web |url=http://www.mobygames.com/game/x-com-collectors-edition |title=X-COM (Collector's Edition) for Windows (1998) |publisher=MobyGames |access-date=2013-08-22 |url-status=live |archive-url=https://web.archive.org/web/20131029190818/http://www.mobygames.com/game/x-com-collectors-edition |archive-date=2013-10-29 }}</ref> ''X-COM Collection'' (1999)<ref>{{cite web |url=http://www.mobygames.com/game/x-com-collection |title=X-COM Collection for Windows (1999) |publisher=MobyGames |date=2001-01-13 |access-date=2013-08-22 |url-status=live |archive-url=https://web.archive.org/web/20170701025414/http://www.mobygames.com/game/x-com-collection |archive-date=2017-07-01 }}</ref> and ''X-COM: Complete Pack'' (2008),<ref>{{cite web |url=http://www.mobygames.com/game/x-com-complete-pack |title=X-COM: Complete Pack for DOS (2008) |publisher=MobyGames |date=2008-09-04 |access-date=2013-08-22 |url-status=live |archive-url=https://web.archive.org/web/20131029191144/http://www.mobygames.com/game/x-com-complete-pack |archive-date=2013-10-29 }}</ref> as well as in ''2K Huge Games Pack'' in 2009.

At least two more major titles have been planned for this series. One of them was ''[[X-COM: Genesis]]'', a real-time strategy and tactics game "going back to the roots but in full 3D."<ref name=tg/> Another was ''[[X-COM: Alliance]]'' (also known as ''X-COM 4'' and the project ''Fox Force Five''), an ''[[Aliens (film)|Aliens]]''-inspired mix of strategy game and first-person perspective [[tactical shooter]], using the licensed original [[Unreal Engine]]. However, both of these projects were cancelled after ex-MicroProse Hasbro Interactive studios were all shut down in 1999–2000 (with ''Alliance'' being later abortively reactivated in 2001-2002 before being quietly cancelled again without any official announcement). Terry Greer, a former senior artist and head of game design at MicroProse UK, disclosed: "We'd also discussed other avenues for future games including time travel, retaking the solar system (with interplanetary distances playing a significant role in recruitment and resources), and resistance movement concept where you had to fight back after the world was taken and humanity was totally under the alien yoke."<ref name=tg>{{cite web|url=http://www.terrygreer.com/xcomalliance.html|title=Terry Greer – Ghosts of games that never were|website=Terry Greer – Past work - XCOM Alliance|access-date=26 August 2017|url-status=live|archive-url=https://web.archive.org/web/20170701060535/http://www.terrygreer.com/xcomalliance.html|archive-date=1 July 2017}}</ref>

In 2010, [[2K Marin]] announced they were working on re-imagining of ''X-COM'', relabeled as ''XCOM''.<ref>{{cite web |url=http://www.xcom.com/ |title=(official 2K Marin site) |work=XCOM |access-date=2012-01-01 |url-status=live |archive-url=https://web.archive.org/web/20120222125547/http://www.xcom.com/ |archive-date=2012-02-22 }}</ref> It was described as a tactical and strategic first-person shooter that would combine elements from the original ''X-COM'' alongside a new setting and viewpoint while keeping some main concepts from the original game series. The setting received a complete overhaul, now based in the early 1960s, with the original XCOM organization being a secret U.S. federal agency. Originally planned for 2011, the game was repeatedly redesigned by different studios before being finally released in 2013 as ''[[The Bureau: XCOM Declassified]]'' for Windows, [[OS X]], [[PlayStation 3]] and [[Xbox 360]].

In 2012, [[Firaxis Games]] (led by MicroProse co-founder [[Sid Meier]]) announced the development of a Windows, PlayStation 3 and Xbox 360 strategy game ''[[XCOM: Enemy Unknown]]'', a "re-imagination" of ''UFO: Enemy Unknown'' with real-time strategic view, turn-based combat and destructible tactical environments more in the vein of the original ''X-COM'' game and set in a more contemporary setting than the ''XCOM'' game by 2K Marin.<ref>{{cite magazine |url=http://www.gameinformer.com/b/news/archive/2012/01/05/february-cover-revealed-xcom-enemy-unknown.aspxd |title=February Cover Revealed: XCOM: Enemy Unknown |magazine=Game Informer |date=January 5, 2012 }}{{dead link|date=April 2025|bot=medic}}{{cbignore|bot=medic}}</ref> ''XCOM: Enemy Unknown'' was released later that same year to critical acclaim, winning multiple "Game of the Year" awards.

Its expansion, ''[[XCOM 2: War of the Chosen]]'', followed in 2017. The next game in the series, ''[[XCOM: Chimera Squad]]'', was released in April 2020, for Windows. Unlike the global scale of previous games, ''Chimera Squad'' focused on a specific city, giving the player control of a diverse squad of humans and aliens. The game introduced several changes to game mechanics, such as replacing randomly generated and customizable squad members with preset and unique soldiers, and utilizing "interleaved turns" (mixing turn order between the opposing teams during combat) instead of a team-by-team turn system.<ref>{{cite magazine|url=https://www.gamesradar.com/xcom-chimera-squad-changes-combat-and-squads-but-firaxis-says-this-is-still-an-xcom-game/ |title=XCOM: Chimera Squad changes combat and squads, but Firaxis says "this is still an XCOM game" |magazine=gamesradar |date=April 22, 2020}}</ref>

===Julian Gollop's unofficial games===
''[[The Dreamland Chronicles: Freedom Ridge]]'' was a game for the PC and [[PlayStation 2]] by Julian Gollop's Mythos Games (creators of ''UFO: Enemy Unknown'' and ''X-COM: Apocalypse''), claimed to having been "essentially a remake of the first ''X-Com'' with 3D graphics."<ref name=codo_about>{{cite web | title =XCom UFO creators strategy game Laser Squad Nemesis | publisher =Codo Technologies | url =http://www.lasersquadnemesis.com/AboutUs.htm | archive-url =https://web.archive.org/web/20090308022717/http://www.lasersquadnemesis.com/AboutUs.htm | archive-date =2009-03-08 | access-date =2007-11-26  }}</ref> ''The Dreamland Chronicles'' was canceled in 2001 and Mythos Games soon ceased to exist.

''[[Laser Squad Nemesis]]'' is a 2002 low-budget PC turn-based tactics game developed by Gollop's next company [[Codo Technologies]] and very similar to the turn-based Battlescape combat system of the first ''X-COM''. In 2005, Codo Technologies and publisher [[Namco]] also released ''[[Rebelstar: Tactical Command]]'', a [[Game Boy Advance]] turn-based [[tactical role-playing game]] that too was reminiscent of the early Battlescape system.

''[[Phoenix Point]]'' is a strategy and turn-based tactics video game for Windows, and OS X that has the open world, strategic layers of the ''X-COM'' style games of the 1990s like ''Enemy Unknown'' and ''Apocalypse'' together with the presentation and tactical mechanics of the more recent Firaxis reboot games.<ref>{{cite web |url=http://www.mcvuk.com/news/read/julian-gollop-s-new-game-will-be-a-cross-between-old-and-new-xcom/0166045 |title=Julian Gollop's new game will be a cross between old and new XCOM |publisher=mcvuk.com |date=2016-04-27 |access-date=2017-06-14 |url-status=live |archive-url=https://web.archive.org/web/20160706171117/http://www.mcvuk.com/news/read/julian-gollop-s-new-game-will-be-a-cross-between-old-and-new-xcom/0166045 |archive-date=2016-07-06 }}</ref> The game was developed by Gollop with [[Snapshot Games]], an independent game studio in Bulgaria.
