- The very end of the opening titles sequence seems to suggest this, with imagry evocative of electronics or networking, finally zooming in on a sphere that reads "<JUBAL> V.184.108.40.206." During the film, Harrison mentions that the Overnight Nation acts "In the name of Jubal." They shout "Jubal!" as a battlecry and behave almost like zombies. Vitalij, a native of the area, is perfectly normal until he sees the complex where the fighting is taking place, and there is clearly a process of some kind that turns him nuts. Brainwashing via nanomachines would explain everything.
Plus, this is Metal Gear, right? Nanomachines is the reason for anything in this series!
- To what end, who knows, but one of the film's trailers does mention the LA-LI-LU-LE-LO, so the film's continuity may very well include them.
