Xenonauts is a turn-based strategy video game developed and published by Goldhawk Interactive. The game is set in an alternate timeline of the Cold War, where the player takes on the role of an elite international force, tasked with defending the planet from an alien invasion. The game combines traditional turn-based tactics with resource management, research and base building. The player must manage a squadron of air and ground units to defend the planet from waves of enemy forces. Combat takes place on procedurally generated maps and is turn-based, with each unit having a range of unique abilities. Between missions, the player can research new technologies, upgrade existing units and base structures, and manage their squadrons. Xenonauts also features a detailed customization system where the player can choose the equipment, skills, and load out of their troops.
