unlike the FPS reboot by 2K Marin (titled “XCOM”), Xenonauts follows the original closely in terms of design, and features Geoscape, base management, and air and ground combat. However, the creators are trying to improve on X-COM in a variety of ways – for example, by adding a directional cover system to the combat system. The game also takes place in the 1979, during the Cold War, and eschews futuristic human technology in favor of more recognizable weapons and vehicles. Xenonauts has been in production for 18 months so far
