Plot On an asteroid, the Terran Federation's Fort Casey is crawling with bugs. The starship Alesia begins to deploy its Mobile Infantry troopers, by dropship, to seize and control the hangar and rescue any survivors. Lt. Daugherty's Alpha Team lands and immediately engages bugs, fighting through to rendezvous with the surviving Fort Casey troopers. After setting explosives charges, the troopers head to the starship John A. Warden for evacuation, only to see it leave dock without them—Minister Carl Jenkins has commandeered the Warden from Captain Carmen Ibanez, sending her to Alesia. Before leaving, Jenkins orders that Major Henry "Hero" Varro, the commander of Fort Casey's K-12 troopers, be escorted to Alesia as a prisoner. Alesia docks with Fort Casey for emergency evacuation of the surviving troopers, and the Fort Casey asteroid is successfully destroyed. While en route to Earth, Alesia is contacted by General Johnny Rico from High Command at L-6 Base. When he orders Alesia to search for the Warden, which has broken all contact, the Fort Casey troopers agree to do so on condition that Varro lead them during the mission. When they find the Warden, Daugherty's team escorts Ibanez to the bridge while Varro's team secures the engine room, both teams finding nothing but dead crewmen and a few dead bugs. Varro finds a deranged Jenkins who warns him—too late—not to power up the Warden because "she" has hacked all the systems. As engines recharge the Warden, an Arachnid Queen inside takes control of all systems and opens bulkhead doors to release her bugs. As Ibanez and the troopers attempt to return to Alesia, the Queen uses Wardens main weapons to destroy the other ship, then flies Warden into a wormhole whose outlet is in near-Earth space. The troopers return to the bridge, where Varro reveals he was arrested when Jenkins had ordered his unit to capture the Queen alive on Fort Casey, but Varro had refused to sacrifice his squad. General Rico deploys 3 starships from L-6 Base in Earth orbit, but the Queen hijacks the Warden's
