So what would you do, if an Alien-vs-human armageddon happened, and humans came out the losers, with only a few 1000 left, you being one of them?
I'd probably dress like a Shinto Monk, and travel the world, looking for other survivors.
So if we are the losers doesn't that mean they either take our planet or enslave us? Or both.
Well, let's say they do take the planet, and enslave anyone they find, you being one of the one's who has yet to get caught. Suddenly, it's a Will Smith movie. Since you're Will Smith, it's your job to shoot aliens and try to free people, ending with a final battle against either a whole bunch of aliens, or their leader, and ends in the freedom of humanity.
How would you free humanity? What weapon(s) would you go with?
