Inside the complex, the two learn from Gianni that Stefania stole a valuable disk containing all of Terminus 4's research on Site Zero and the T'lan, deleting all backups. The U.S. military wants the information, so they send in a team to retrieve the disk before they order a nuclear strike. Deep into Site Zero, Alex is captured by Solus. As Derrick makes his way through alone, he witnesses Stefania's execution after she turns the data over to the military. Derrick travels on foot to the silos but arrives to find Gianni's squad decimated. The rockets are launched, and the T'lan are scattered all over the world. Derrick enters the heart of Site Zero to stop Nexus but is challenged by Solus. During the fight, Solus kills Alex, and the U.S. military launches a nuclear strike in a last-ditch effort to destroy Site Zero. The resulting explosion reacts with Solus' shield and Derrick is sent 15 years into the future.
