I don't play any FPS (or anything outside air SIM) but I feel like those are scenario drawn to raise some interest in the public. They pick some trends in international affairs and use it as a way to "fashion" their games. It's only average public fantasma put in 3D animations.
What would you think if your favorite game dev (outside CoD team

) would pull out old Ripley out of her space travel box and let you be her for one more roll amid spiting aliens ? You'd get bored
The good point is that one day we might see some US troop storming some "Standard & poor" buildings to clean it out of some Alien's Viral infested trader.
I might try FPS that day
