Phaeton tells the captive Marsh of his plans to destroy the world. To prevent this Winfield is sending a few ExoSquads into Chicago to go after Phaeton. O'Reilly fixes the jumptroopers shuttle so that the remainder of Charlie Company, along with Bronski, can also make it there. Despite Livia's protestations, Phaeton will not leave the city. When he attempts to activate the doomsday device, he finds it has been sabotaged and he knows it was Livia who did it. Able Squad battles their way through the tunnels beneath the city, and Nara, Marsala, and Takagi reach the main chamber just as Phaeton is about to flip the now functional switch to the doomsday device. A battle ensues which ends when Nara, at first instinctively using her strange powers to stop Phaeton, kills him.
