The EDF defends a fictional city called New Detroit against an alien invasion, aided by bio-engineered terrestrial insects. The Player goes by the name of Lightning Alpha, leader of an elite team of fighters, known as Strike Force Lightning. Along with two squad mates, Lightning is (usually) aided by local EDF fighting forces in the area, though they are poor compared to Lightning.\r
\r
The story is divided into three separate chapters, which are divided into five separate missions. The first chapter is akin to an introduction to the game, while the second chapter has Strike Force Lightning moving across industrial New Detroit to discover the fates of several downed Landers scattered across the city, as well as their pilots and cargo. Only one of them is salvageable, and it becomes piloted by the cool-headed Captain Sully, a character that returns in later missions. The third chapter follows the story of Lightning finding and transporting The Cube to a nest in central New Detroit. Before it is deployed, an Ant Queen emerges from the nest, forcing Lightning to do battle with it to secure the drop zone.\r
\r
Once the Queen and her minions are dead, The Cube is dropped in the middle of the nest, and Lightning quickly makes their way to the evacuation zone. As their transport Lander is about to begin its descent, a new Ravager ship (akin to a much larger and more heavily armed version of a Ravager Carrier) appears in the skies, downing the Lander. Lightning rendezvous with Echo and X-Ray squads, EDF troopers who were stuck in Central Detroit without evacuation, and they make their way to another evacuation site where they must defend against several Hectors (large Ravager Mech Walkers) until they are rescued by Lander Captain Sully, who (at the time) violated an EDF No-Fly Zone without remorse.
