Even though Laser squad was the first game of this genre (squad fighting strategy), UFO was the first one that was successful. Ask any serious gamer about the X-Com game and You'll see a smile on his/her face. X-Com is one of my all time favorites. The game puts You in role of head commander of X-Com, Terran special forces unit specialized for fighting the aliens. You can build bases, research new equipment and alien technologies, fight aliens on ground and in air, defend civilians in cities, attack alien bases... The combat mode is the one that made this game so popular - You get to control Your squad in turn-based combat. To see this and a whole lot more download the game and play it! Note: The game might shutdown sometimes or make an illegal operation. To avoid this save game often and just reload if any errors occur.
