Xenonauts 2

Xenonauts 2 is a strategy game that puts you in charge of a multinational military organization tasked with eliminating an extraterrestrial threat. Working from the shadows, you must seek out and engage the growing alien presence wherever it appears. Expand and manage a covert network of bases across the globe. Pursue research and development to bridge the technological gap with the alien invaders. Train, arm, and command your ground troops wherever the alien threat emerges.

It is 2009 - the Cold War continues, and the Berlin Wall still stands. In the shadows, a secret organization works beyond arbitrary political boundaries to gather information about a greater threat to humanity. Mysterious sightings of unidentified flying objects and unknown beings have grown more common, coinciding with escalating international tensions and panic.
