Under the control of Eric Nishijima and developed by Robert Schroeder, who claims it is his life's greatest invention, it aims to use a particle accelerator to destroy the Hell's Gate and thus eradicate Contractors. This was attempted five years previously with Heaven's Gate and the Jupiter Ring, but failed due to the accelerator's destruction. The wall surrounding Hell's Gate is intended not only to stop people from accessing the area, but it is also a fortress designed to protect the Saturn Ring's particle accelerator and a second accelerator concealed within the facility that acts as a back-up in case of a repeat attempt to destroy the accelerator.
