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.
XCOM: Enemy Unknown blends strategic base management with turn-based combat in unique and addictive game play.
Strategy Evolved: XCOM: Enemy Unknown couples tactical turn-based gameplay with incredible over-the-shoulder action sequences and on-the-ground combat.
Strategic Base: Recruit, customize and train unique soldiers, research new and exotic technologies, and manage your personnel as you build and expand your XCOM headquarters.
Tactical Combat: Direct soldier squads in tense turn-based ground battles. Explore maps shrouded by the "fog of war" to discover and engage enemy forces.
Worldwide Threat: Combat spans the globe as you use the Skyranger to deploy squads to engage the enemy on over 70 unique maps, detect and intercept the alien UFOs in the skies, and interact and negotiate with governments around the world.
XCOM's soldiers are humanity's first and last line of defense against the alien invaders and serve as the primary and most valuable combat units in XCOM: Enemy Unknown. Soldiers are initially fielded in squads of four but this number can be expanded up to a maximum of six as the game progresses. Soldiers' deaths are permanent, but those who survive long enough to graduate from the Rookie rank will gain one of the following specialized classes:
These veterans can bring a staggering variety of deadly abilities to the battlefield as they rank up. Soldiers can be further customized through the option to change their physical appearances and names and outfitting them with the latest weapons and equipment developed by your research team.
By researching new tech, players will gain access to upgrades such as body armor and weapons, as well as gaining access to new facilities. By interrogating captured live aliens, players gain Research credits which can greatly speed up the research process.
Players will fight a multitude of alien species including:
- Thin Man
- Balanced Classic Difficulty Strategy Guide
- Impossible Difficulty Strategy Guide
- Impossible Difficulty Combat Guide
- Random vs Seeded Outcomes Guide
- Squad Tactics
