People have finally met intelligent life on another planet. But these creatures turned out to be not at all friendly, as soon as the first contact happened, the ship of people was destroyed. A fleet of ships is heading for Earth, and you must defend your base at all costs. As soon as the ships reached orbit, capsules with a landing force fell to Earth. Humanity first encountered such an enemy and you need to be as careful as possible, since practically nothing is known about the enemy. Kill all the xenomorphs and defend the base from the attack.
