Most-played X-COM games
X-COM: Terror from the Deep
DOSTurn-based strategy
X-COM: Terror from the Deep is a turn-based strategy game developed and published by MicroProse for DOS. It is the second main entry in the X-COM series and moves the alien conflict from the skies and fields of Earth to the oceans and coastal regions. Players manage a global defense organization, investigate underwater activity, develop technology, and lead soldiers through detailed tactical missions. The game combines a strategic management layer with squad-based combat in an isometric environment. Its harsher combat, underwater setting, and expanded research systems were ambitious, although its high difficulty and similarities to its predecessor divided critics. It remains a notable example of complex 1990s PC strategy design.
X-COM: Apocalypse
DOSTurn-based strategy
X-COM: Apocalypse is a science-fiction strategy game developed by Mythos Games and published by MicroProse for DOS. It combines turn-based management of an extraterrestrial defense organization with real-time tactical battles inside a futuristic city. The player must investigate alien activity, develop weapons and equipment, manage funding and organizations, and protect Mega-Primus from escalating incursions. Its city simulation, faction diplomacy, and optional real-time combat made it a substantial departure from the earlier games. Reception was generally positive for its ambition and depth, although the interface and real-time battles were considered less accessible than the turn-based combat of its predecessors.
UFO: Enemy Unknown
DOSTurn-Based Tactics
UFO: Enemy Unknown is a turn-based tactics and strategy game developed by Mythos Games and published by MicroProse. The player commands X-COM, an international organization created to investigate and stop an escalating alien invasion. Its two-layer design alternates between a strategic world map and detailed tactical missions. Players research captured technology, expand facilities, manage funding, and direct soldiers in squad combat. The game was widely praised for its depth, atmosphere, meaningful consequences, and demanding difficulty, and it became a defining title of 1990s strategy gaming.
