There won't be many but, when Skynet becomes self-aware and tries to wipe out humanity, there will be a few survivors. They'll have to figure out how to live in a new world - one where they are constantly hunted by the machines - until they can turn the tide against their metal overlords. If they're looking for a place to hide, they'd better stick to the planet's underground bunkers because - thanks to the Navy's new robot shark-drone - the oceans will not be safe.
