Arc 21The Federation Falls
William exposed the Federation’s role in the Buenos Aires disaster, seized control of its government, and prepared Umbrella and the New Federation to exterminate the Arachnid Swarm. As the campaign began, John and Ivan’s forces landed on OM-1 to hunt Bihankoto.
- William captured the brain bug and used its testimony, Carl’s account, and Serena’s broadcasts to reveal that the Federation had allowed the Buenos Aires meteor through.
- William led Umbrella’s forces to Geneva, where John’s troops seized Federation headquarters and Ivan’s squad captured the Aegis of Zeus.
- William publicly tried and sentenced the former Grand Marshals and generals who knew about the Buenos Aires incident, then promised reforms to the New Federation government.
- William arranged inter-universe trade with Constantine and learned that Halsey, Rebecca, and 049 had developed the Exterminator virus to kill the Arachnids and prevent them from reproducing.
- Halsey told William she could build a Quantum Bomb prototype within half a year, and William agreed to transfer Li Mu and have another child with her after she completed it.
- Umbrella and the New Federation prepared the Exterminator virus, opened applications for Mars immigration, and dispatched forces to spread the virus across Arachnid-controlled planets.
- John and Ivan led troops onto OM-1 to search for Bihankoto, and Rico detonated an Individual Nuclear Bomb against an approaching Arachnid swarm.
