Xenonauts 2

Xenonauts 2 is a strategy game where you manage a multinational military organization fighting an extraterrestrial invasion. The story takes place in 2009, during an alternate Cold War where the Berlin Wall remains standing. As unidentified flying objects and mysterious beings appear, a secret group works to eliminate this threat from the shadows. You must build and oversee a global network of covert bases to track alien activity.

You command turn-based tactical battles against various alien species. By recovering research samples and performing autopsies on alien bodies, your scientists can improve your equipment to better face your technologically superior foes. You also fight human agents called Cleaners who assist the invasion. You directly control your fighter wings and train ground troops to win a simulation of asymmetric warfare.
