Xenonauts is a turn-based single-player strategy game developed and published by Goldhawk Interactive. It was released on June 17, 2014 on Steam and GoG. It is similar to the original X-Com game. Players control a multi-national military organisation defending a Cold War-era Earth from alien invasion, using small squads of persistent soldiers to eliminate the extraterrestrials and recover their technology in turn-based ground combat.
The history of the Xenonauts organization is shrouded in mystery. All that is known about the organization is that it is a hidden organization that was the only group that was able to successfully down a UFO in the opening month of the initial Alien appearance. With this they contacted the major world powers and demanded funding and equipment in exchange for combating the Alien thread, the world powers accepted.
