Armada

Zack Lightman lives for the thrill of science fiction, but his reality is far from the adventures he craves. He knows the difference between fantasy and reality, or so he thought. When a real alien spaceship, identical to those in his favorite video game, appears, Zack's world is turned upside down. Suddenly, his gaming skills are Earth's last hope against an alien invasion, thrusting him into the hero role he only dreamed of.
