That's $19.99 for the first week!Xenonauts is a spiritual successor to the classic X-Com strategy games from the 1990s. We aim to improve the graphics, add new content and streamline the interface whilst still retaining all of the key mechanics of the original games. Devoted fans should love this game, but we're also keen to introduce the joys of old-school grand strategy to a whole new generation of players who might not otherwise experience it! In this robust strategy game you control a multi-national military organisation defending a Cold War-era Earth from an alien invasion, using small squads of persistent soldiers to eliminate the extraterrestrials and recover their technology in turn-based ground combat. A detailed strategic layer allows you to co-ordinate the defence of the planet, using your interceptors to shoot down UFOs and researching captured artefacts to learn about your foes and unlock new combat equipment to use on your missions. The game comes with a full MP3 sountrack!The alien overlords' plan was as simple, as it was brilliant: "wait for the 2014 DRM-Free Summer Sale to start on GOG.com, and conquer the Earth with minimum resistance while everyone is busy tracking the Flash Deals". Stay vigilant, defender of our home planet! Only you can foil the extraterrestrials' scheme and show them that the human race is not to be messed with, in Xenonauts, for $19.99 on GOG.com. The 20% off special release discount will last until Monday, June 23, at 1:00PM GMT.
