X-COM is a series of six strategy games started by Mythos Games and MicroProse in 1993. The first three titles were tactical games while the fourth was a strategy game. The fifth game was an online multiplayer game that followed in the same vein as the first three. The sixth game, a third-person shooter, was developed and published by Infogrames in 2001.
All of the titles were developed for the PC, with a few ports to the PlayStation and Amiga. The first three titles were originally developed to run under MS-DOS, and were later ported to run under Microsoft Windows using DirectX.
- Main series
- UFO: Enemy Unknown (1993)
- X-COM: Terror from the Deep (1995)
- X-COM: Apocalypse (1997)
- X-COM: Interceptor (1998)
The first installment, UFO: Enemy Unknown in Europe (also known as X-COM: UFO Defense in North America), was written by a team led by Julian Gollop. MicroProse quickly had an internal team create the sequel X-COM: Terror from the Deep. Subsequently, the Gollop brothers went straight to work on X-COM: Apocalypse, which would end up being the third in the series when released in 1997. At the end of 1998, MicroProse was bought by Hasbro Interactive, which released two more X-COM games (Interceptor and Email games).
- Independent titles
X-COM: Genesis, a RTS game, was to be the fifth installment to the main series, but was canceled during development when Hasbro Interactive shutdown the former MicroProse development studio in December 1999.
X-COM: Alliance, a FPS game, was the second and final game to be canceled during Hasbro Interactive's closure.
