"...the campaign is full of tense moments that are sure to keep you coming back for more." - IGN.com

"A wonderful and worthy strategy game with a layer of campy charm that makes the stone-faced seriousness of the game's characters all the more endearing. It's also remarkably accessible, thanks to a great interface that feels comfortable whether you're using a keyboard and mouse or have a controller in your hand." - Gamespot.com

Threatened by an unknown enemy, the Earth’s governments unite to form an elite paramilitary organization, known as XCOM, to combat this extraterrestrial attack. As the commander of XCOM, you control the global defense team in a battle against a terrifying alien invasion by creating a fully operational base, researching alien technologies, planning combat missions, and controlling soldier movement in battle.

Key Features:

  • Worldwide Threat: Combat spans the globe as the XCOM team engages in over 70 unique missions, interacting and negotiating with governments around the world.

  • Strategic Base: Recruit, customize and grow unique soldiers and manage your personnel. Detect and intercept the alien threat as you build and expand your XCOM headquarters.

  • Strategy Evolved: XCOM: Enemy Unknown couples tactical turn-based gameplay with incredible action sequences and on-the-ground combat.

  • Tactical Combat: Direct soldier squads in turn-based ground battles and deploy air units such as the Interceptor and Skyranger.

Great strategy game.

For almost half the game, you're running a base, researching, funding lots of new weapons, managing a fleet of fighter craft and most of the time trying to keep a small number of rich and powerful funding nations happy enough to keep on funding you. For the other half, you're taking a small squad of soldiers out into the field for some turn-based combat, where the real fun begins. If you are into the genre definetily get this game.


addicting, with a few minor bugs

Having never played the XCOM series, I thought I'd give Enemy Unknown a shot when I saw the trailer for XCOM 2. I regret not trying it before, and it's been fun trying different techniques to clear the aliens out in the open and in close quarters. My two biggest gripes: - RNG causing you to miss high percentage shots, reclass your soldiers to excess specialties, etc. - I experienced the muton bug in a save file, and had to creatively find a solution to work around it (using a heavy's rocket)


Best strategy game of its genre

XCOM:Enemy Unknown is a turn-based squad strategy game, to those unfamiliar. Although strayed from the original XCOM, a great game nonetheless with a lot of thought needed in each alien encounter, but also in the macro-management of the entire operation in regards of gear, research, base construction etc. The gripes i have with this game is in the lack of versatility in your gear,research and construction: Why can't i just give a recruit the shotgun instead of waiting for him to level up? or why can't i recruit scientists and engineers myself like i can with soldiers? why only one base and one skyranger? Besides that it's a great strategy game and is even better with the Enemy Within expansion. A truly great game for strategy lovers.


one of my fevorites games of all times.

unlike a-lot of today games this game is a gem, well made and polished story and mechanics who makes you want to play it again and again. this is how games should be made, not instant release full of bugs and "DLC" patches to leach $$ if you like tactical-strategy games you will like this one, you will need to mange your economics on base and further your tec advance, and on the same time to control your squad on the battlefield. i highly recommend it!


great remake for xcom! score 95!
