Aliens versus Humans is a turn-based strategy in the spirit of the cult XCOM: Enemy Unknown, where you have to protect Earth from an alien invasion. You have been hired by the United Countries of Earth (UCE) to defend our planet. Your task is to build bases around the world to detect alien "teleportation events". Upon detection, you must dispatch a personal squad of soldiers to eliminate the alien threat and capture any alien technology that will aid in their further destruction.
