The rebuilt city of Boston, formally designated Boston-02, is the site of Sanguine’s main base of operations. The base itself actually lies underneath the city and is mainly accessible through hidden submarine docking bays in the harbor. The base sprawls nearly a kilometer into the earth at its deepest point and contains the facilities necessary for the development, storage and deployment of the Titans. The base also contains multiple research labs and engineering bays, along with the command bridge, from which Sanguine’s operations director can observe and command during combat. It is on the command bridge where the famed F.A.T.E. supercomputer system is also situated. The three computers (named Clotho, Lachesis and Atropos) are a programming marvel, with decision making capabilities so advanced they have been running the municipal government of Boston-02 for the past eight years.
Boston-02 has been designed with Titan on Fury combat in mind. Scattered throughout the city center are multiple trap door launch ports that connect to the Titan launch bay through an maze of Titan sized launch tunnels. This infrastructure allows for the Titans to be launched directly up into combat from Sanguine’s underground base. As well, the city is littered with umbilical cord ports and weapons support caches, allowing the Titans mobility and the ability to receive new weapons and ammunition throughout the battle.
The amount of defenses in Boston-02 is no coincidence, Sanguine is sure that the Furies will strike this city with all their might. They know this because at the very innermost layer of the base, beneath every last defense mankind can muster, is an chamber code named “Tartarus”. Should a Fury every breach that chamber, Third Impact and the death of humanity is all but assured.
