Despite the cult following and great praise on most of the mainlineXCOMentries it hasn’t always a smooth ride for the series. There were two canceled projects, disagreements between developers which unfortunately carried over into one of their games, and some badly reviewed games.
Thankfully, the series has found its way back with the rebooted series released on the PC and on consoles lets take a look at all of the best and worst games in the series.
Updated by Michael Llewellyn on March 7th, 2021:The XCOM series continues to find new fans of its turn-based strategy series. It’s unsurprising as the series remains one of the most influential of all time, inspiring other modern hits like Mario + Rabbids: Kingdom Battle and Empire of Sin. However, there something about fighting off an alien invasion in videogames that’s appealed to gamers since the days of Space Invaders and Galaga. With the addition of spiritual successors and a brand new spin-off title let’s see where these games place in one of the most iconic strategy games of all time.
12X-COM: First Alien Invasion
X-COM: First Alien Invasionwas a two-player turn-based strategy game that required email responses to play. It was a simplified version of its mainline predecessors which meant that nearly anyone could play the game without too much trouble or worrying about the complexities of the mainline series.
The main advantage of using email as the platform for gaming sessions is that even the most underpowered PCs could play it. However, for fans of the series, there was just too much missing from the core series to make it worthwhile.
11X-COM: Enforcer
X-Com: Enforcerwas released on the PC in 2001 and was the final entry in the original series developed by MicroProse. Unfortunately, despite being set in theX-COMuniverse the game has very little in common with other entries in the franchise.

The game was a straight-up run and gun third-person action shooter. None of the strategy elements were present and there was very little thought involved when working through the game’s levels.X-Com: Enforcerwas spliced together in a rush using leftover resources of two canceled gamesX-COM: GenesisandX-COM: Alliance.
10X-COM: Interceptor
X-COM: Interceptoris aWing Commander-like space flight simulator with elements of the mainline series and was released in 1998 on the PC.Interceptor’s timeline is a prequel and is set before the events ofX-COM: Apocalypse.
In addition to the space flight simulation aspects, the game expands on the business management where you are managing space colonies instead of a base on earth. It wasn’t a terrible idea for anX-COMtitle, however, the execution of the story was so bad that it made theCommand and Conquercutscenes seem Oscar-worthy by comparison.
9X-COM: Apocalypse
X-COM: Apocalypsewas released in 1997 on the PC and was the third title in the series. It’s a traditional turn-based strategy game just like its previous two entries – although it did have an additional real-time option.
Unfortunately, it suffered from a troubled development due to disagreements between Mythos Studios and MicroPose both having very different visions. This did have an effect on the final product with the game’s city simulation and management aspect being at odds with a full-scale alien invasion many critics considered too ambitious.
8XCOM: Chimera Squad
Released on the PC in 2020,XCOM: Chimera Squadis a tactical turn-based strategy game based after the events ofXCOM 2: War of the Chosen.Even thoughChimera Squadis played out on a much smaller scale than the mainline series the core gameplay remains very similar.

As a result, veterans of the series will feel right at home with its strategy elements outside of theChimera Squad’s combat in the field. It does lose a lot of the tension and darker elements that are usually associated with the series due to the misplaced humor,the characters, and weak voice acting but it’s still a solid strategy game in its own right.
7The Bureau: XCOM Declassified
The Bureau: XCOM Declassifiedwas a spin-off title that was developed by 2K Marin - who worked onBioshock 2- and released for the PlayStation 3 and Xbox 360 in 2013. The game’s events take place in the 1960s before the events of the rebootXCOM: Enemy Unknown.
As a third-person tactical shooter,The Bureauplayed quite differently from the turn-based strategy seen in the mainline entries. It retained important gameplay mechanics like permadeath for squad members along with some intense gameplay sequences. Unfortunately, certain elements didn’t quite work and the sense of loss one would feel when losing a companion character in the mainline series is lost onThe Bureau. That being said, its strength lies in its storytelling and the twist ending helps flesh out the overall narrative of the rebootedXCOMseries.
6X-COM: Terror From The Deep
X-COM: Terror From The Deepis the second game in the series and was released in 1995 on the PC and was later ported to the PlayStation in 1996. This time game takes place underwater and requires the player to participate in a real-time base building and the series staple turn-based combat.

Despite the underwater setting,Terror From The Deepfelt the same as its predecessor. However,X-COM: UFO Defenseis still considered to be one of the best tactical video games ever developed and the difficulty is high enough to challenge even the most seasoned gaming strategists.
5XCOM: Enemy Unknown
Released in 2012 on the PlayStation 3, Xbox 360, and the PC,XCOM: Enemy Unknownwas the first game in the rebooted series developed by Firaxis.Enemy Unknownwas the recipient of several games of the year awards and received huge critical acclaim from fans and critics alike.
Enemy Unknownmanaged to take everything that was so good about the original games and improved nearly every aspect of it. In addition, Firaxis proved that complex strategy games could work just as well on consoles as they did on the PC which was a feat in itself.
4X-COM: UFO Defense
X-COM: UFO Defenseis also known asX-COM: EnemyUnknownwas released for the PC in 1994. It is still considered one of the most influential and greatest PC videogames of all time. It was later released for the PlayStation and was one of the few games to make use of the PlayStation Mouse.
Despite its age, the game is incredibly complex and deep combining its brilliant turn-based combat system and its business management sim aspects.UFO Defensepulled off a sense of real tension, horror, and the fear of the unknown that has continued with the rebooted Firaxis series.
3XCOM: Enemy Within
Released in 2014 for the PlayStation 3, Xbox 360, and the PC,XCOM: Enemy Withinis an expanded version ofEnemy Unknown.However, it added enough significant content in terms of story and depth that it stands alone and above the original game in every way.
Enemy Withinadds new resources, robotic units, brand new trooper classes, and a new enemy faction called the EXALT. The game also reintroduces the random Base Defense missions which can end a player’s game immediately when failed. Furthermore,Enemy Withinadded new story elements and 47 brand-new maps.
