X-COM: UFO Defense [PC] [v1.14]

X-COM: UFO Defense is a foundational PC strategy title that established the blueprint for turn-based tactical and management hybrids. Set during an alien invasion, the game places players in control of a global defense organization, balancing real-time geoscape decisions with tense, grid-based combat missions. Its depth comes from resource management, research progression, and the permanent consequences of battlefield losses, reinforcing high-stakes decision-making. Procedurally generated missions and unpredictable enemy behavior enhance replay value, while its layered systems demand long-term planning. Even decades later, it remains a benchmark for strategic design and a direct influence on modern tactical PC games.
