The X-COM core series consisted of four main games published by MicroProse: UFO: Enemy Unknown (also known as X-COM: UFO Defense and originally released in 1994 for the PC, with later ports for the Amiga and Sony PlayStation), X-COM: Terror from the Deep (PC in 1995 and the PlayStation in 1996), X-COM: Apocalypse (PC, 1997) and X-COM: Interceptor (PC, 1998).

The premise of the franchise is that a mysterious alien invasion began in 1999 (a near future at the time of the first game's release). In response, a coalition of funding nations clandestinely create an elite paramilitary organization codenamed X-COM (an abbreviation of "Extraterrestrial Combat Unit") as humankind's last hope. The player is charged with leading this secret force, tasked with a mission to engage and research the alien threat. At the end of the successful game, the X-COM manages to capture and reverse engineer enough of the invaders' technology to decisively turn it against them. The sequels took the fight against new alien invasions underwater (Terror from the Deep, set in 2040), into a futuristic megacity (Apocalypse, set in 2084), and eventually into space (Interceptor, set in 2067, which actually makes it a prequel to Apocalypse).

UFO: Enemy Unknown, featuring a turn-based ground combat system, remains by far the most popular and successful game in the series and has been often featured on the various lists of best video games of all time. The first sequel, Terror from the Deep, was quickly created by MicroProse's internal team and 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 combat system and shifting the aesthetics to a retro-futuristic style. However, despite being developed by Julian Gollop's British studio Mythos Games, the original creators of Enemy Unknown, it failed to repeat its smash success. The last released X-COM main game, Interceptor, constitutes a hybrid of a strategy game and a space combat flight simulator. After Interceptor, Hasbro Interactive purchased MicroProse, acquiring its studios and the X-COM brand, and, according to GameSpy, "there was wild talk of X-COM toys, comics, and cartoon shows." A budget range, turn-based tactical play-by-mail multiplayer game 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.

Two more major titles were planned for this series: X-COM: Genesis (a real-time strategy and tactics game) and X-COM: Alliance (a tactical, first-person shooter with an action role-playing game elements). However, both of these projects were cancelled after ex-MicroProse Hasbro Interactive studios were all shut down in 1999-2000 (although Alliance has been later abortively reactivated in 2001-2002). The X-COM games were also released as part of four compilation releases: X-COM (Collector's Edition) (1998), X-COM Collection (1999) and X-COM: Complete Pack (2008), as well as in 2K Huge Games Pack in 2009.

In April 2010, 2K Marin announced they were working on re-imagining of X-COM, relabeled as XCOM, to be released for the PC, PlayStation 3 and Xbox 360. It is described as a tactical and strategic first-person shooter supposed to 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 is getting a complete overhaul and now based in the early 1960s, with the XCOM being a U.S. federal agency. Originally planned to be released in 2011, the game is currently scheduled for August 2013, renamed as The Bureau: XCOM Declassified.

In January 2012, Firaxis Games (led by MicroProse co-founder Sid Meier) revealed to be developing a PC, PlayStation 3 and Xbox 360 strategy game XCOM: Enemy Unknown, a "re-imagination" of UFO: Enemy Unknown that is going to feature real-time strategic view, turn-based combat and destructible tactical environments more in vein of the original X-COM game. It is also set in a more contemporary setting than the XCOM game by 2K Marin. XCOM: Enemy Unknown was released on October 9, 2012 to critical acclaim, winning multiple "Game of the Year" awards. Julian Gollop hailed it as "a phoenix rising from the ashes of the X-COM disaster", saying that "it’s amazing that after 20 years, a brand that had gone so badly in the wrong direction has finally been put right."

Literature

There are two X-COM novels based on the first game in the series: Diane Duane's X-COM: UFO Defense - A Novel (1995, ISBN 0-7615-0235-1) and Vladimir Vasilyev's Enemy Unknown (1997). According to Rock, Paper, Shotgun's negative review of Duane's novel, it is hampered by a poor understanding of the game, a lack of focus, emotional resonance and tension, and an unstructured plot. MicroProse's John Possidente also wrote three short stories ("Decommissioning", "Manley's Deposition" and "Moray in the Wreck") taking place between the events of the first two games in the series.

Intellectual property rights

The trademark for the X-COM name was filed on May 25, 1995, by MicroProse Software. According to Julian Gollop, "They wanted us to do a deal where we would sign over any rights that we might have in return for some cash plus a high royalty on X-COM: Apocalypse. They more or less insisted on it, otherwise they were threatening to cancel the Apocalypse project, so there was a lot of bluff involved." Following the acquisition and subsequent merger of MicroProse with Hasbro, the X-COM intellectual property ("IP") was also transferred to Hasbro Interactive on August 19, 1998. Due to financial difficulties, Hasbro Interactive was sold to Infogrames Entertainment, SA on January 29, 2001. As part of this transfer, the X-COM IP was legally transferred to Infogrames on December 21, 2001 (shortly thereafter, Infogrames was renamed Atari, SA). In 2005, Atari, SA transferred several IPs to Take-Two Interactive Software, Inc. and X-COM was transferred with them on June 12, 2005.

The X-COM IP is currently owned by Take-Two and its subsidiaries; in 2007 there were unconfirmed rumors that Irrational Games (who are owned by Take-Two) were developing a new X-COM title. In May 2007, 2K Games (a subsidiary of Take-Two) inherited the X-COM franchise and re-released Terror from the Deep on Steam. In September 2008, UFO: Enemy Unknown, Apocalypse, Interceptor and Enforcer were also re-released as downloadable titles.

Spiritual successors

Because of the series' popularity, various developers have created spiritual successor games similar in theme and tone of the X-COM games (sometimes called "X-COM clones"; Gollop also himself called turn-based tactical game genre in general as "sons of Rebelstar" in a reference to one of his earlier games). The level to which they borrow from the original series varies.

Commercial

• Abomination: The Nemesis Project is a real-time tactics / action game developed by Hothouse Creations and released by Eidos Interactive for the PC in 1999 that has been touted as "X-COM meets Day of the Dead in real-time."

• Aliens versus Humans is a 2012 UFO: Enemy Unknown clone for the iPhone and iPad. Gollop highlighted it an example of "indie remakes" in his "X-Com legacy" chart.

• Guardians: Agents of Justice is an unreleased game by Simtex and MicroProse, which was described as "a superhero version of X-COM."

• Incubation: Time Is Running Out is a turn-based combat PC game that was considered to be "what X-Com Apocalypse should have been". It was developed and released by German company Blue Byte Software in 1997.

• Laser Squad Nemesis is a 2002 turn-based low-budget PC turn-based tactics game developed by Gollop's new company, Codo Technologies, very similar to the Battlescape ground combat system of the first X-COM game.
  • In 2005, Codo Technologies and publisher Namco also released the Game Boy Advance turn-based tactics game Rebelstar: Tactical Command, which was as well reminiscent of the early Battlescape system.

• The Dreamland Chronicles: Freedom Ridge was a strategy game for the PC and PlayStation 2 by Julian Gollop's Mythos Games (creators of Enemy Unknown and Apocalypse), claimed to having been "essentially a remake of the first X-Com with 3D graphics". The Dreamland Chronicles was canceled in 2001 and Mythos Games soon ceased to exist.

• UFO: Aftermath is a 2003 single-player PC strategy and real-time tactics game which was heavily influenced by the X-COM series and used elements of the Mythos Games' canceled The Dreamland Chronicles. It was created by Czech company ALTAR Interactive and published by Tri Synergy.
  • Aftermath was followed by two sequels: UFO: Aftershock in 2005 and UFO: Afterlight in 2007.

• UFO: Extraterrestrials, a PC strategy / turn-based tactics game that is an unofficial sequel to the X-COM games, developed by Czech developer Chaos Concept and released by Tri Synergy in 2007.
  • The follow-up game, UFO2Extraterrestrials: Shadows over Earth was supposed to be released in Q4 of 2012; as of April 2013, its current status is unclear.

• UFO Online – Fight for Earth is an upcoming, browser-based massively multiplayer tactical game. Gollop called it "actually more a clone of Incubation." It is free-to-play, but will use a micropayment system to generate revenue.

• Xenonauts is an upcoming PC strategy game in development by British independent studio Goldhawk Interactive, again heavily influenced by the X-COM series. It is being marketed as a Cold War-era (1979 instead of 1999) re-imagining of the original UFO: Enemy Unknown and an answer to 2K's XCOM which has alienated some of the X-COM fanbase due to its FPS-based gameplay. The game missed several release dates, but is still in active development.

• Xenowar is an open source, simple tactical game for the Android and Windows operating systems.

Non-commercial

• UFO: Alien Invasion is a free-to-play, open source cross-platform strategy / turn-based tactics game heavily influenced by the X-COM series.
