XCOM: Enemy Unknown is a remake of the classic 1994 hit game UFO: Enemy Unknown which is widely regarded as one of the best games ever made. It expands on that legacy with an entirely new invasion story, with more enemies and technologies to defend Earth. In XCOM: Enemy Unknown, you are the commander of XCOM, the most elite paramilitary organization in the world dedicated to stopping the alien invasion. Your soldiers are fighting an uphill battle as the aliens use superior armor, technology, and weapons.

In this remake of the classic franchise, players will execute their strategies from the XCOM base by researching new weapons, armor, and ships, building new facilities, manufacturing new aircraft and weapons, and directing their agents on combat missions. New soldiers start from the rank of Squaddie and can level up through 7 ranks to Colonel. Each soldier can specialize in a specific combat style be it Assault, Heavy, Sniper or Support. Every decision is important, and sometimes a single simple choice can be the difference between victory or defeat. With the doom clock ticking, will you be able to push back the aliens and save humanity from annihilation?
