Dont quote me on this but im think I remember seeing SNN referenced to on the BO terminal as "The Rising Sun Facility, Japan". Hopefully that will jog someone memory on here, because I dont remember much about this.
On another note, do we actually know what the FIRST EVER breakout was? Was it originally on the moon when Sam first gain power tgrough the pyramid?
OH lol and while where on that, I noticed some foreshadowing of the story in Kino. Remember the poster with the Pyramid-Woman? I think it was called "Pyromogul" or something. It showed what looked like an omnipotent figure with a pyramid on her head, seems to me like a reference to Sam, a nod to what was later discovered in Moon, just shows that Treyarch really did know what they were doing with the story since Kino.
