Someone on the last page said Mistral's chapter is set in Africa. It's actually in a splinter state in Georgia, and Georgia is between Eastern Europe and Western Asia, bounded by the Black Sea, Russia, Turkey, Armenia, and Azerbaijan.
Also, regarding Armstrong, and how people take to him: I don't agree with him, and he sort of represents everything I loathe in politics, but like any good politician, he has alluring charisma, and you can't help but want to see more of him. He stole the show in every cutscene where he appeared (well, except the one in the Mexican lab, I guess), and he was incredibly fun to fight, both thematically and mechanically. I just beat him on Very Hard last night, starting the battle with zero nanopastes, and it was tense as hell until I cut open the boulder to get more.
What I don't get is how Armstrong so blatantly participated in what was happening at the Pakistani base. He was right there on the ground in plain sight. It's true Air Force One had already turned back for America by the time Armstrong stepped out of Excelsus, since U.S. intelligence had already picked up on Raiden fighting the Desperado terrorists there. But are we to believe U.S. intelligence -stopped- watching the base after Air Force One turned back? Because if they kept tabs on it, they would've seen Armstrong emerge soon enough.
In one of the codec calls, your supports doubt Armstrong is at the base, saying he'd more likely have henchmen handle the dirty work than risk blowing his own cover. At the same time, they acknowledge there would be a need for someone to orchestrate activities at the base. They also express doubt Armstrong would put up any sort of fight.
Clearly they were wrong on all fronts. But I still don't understand how Armstrong has no qualms being seen at the site of the assassination attempt on President Hamilton.
