If the robots rise up against the humans, there will be war, at least with the survivors, the humans that aren’t wiped out by being at the wrong place at the wrong time, or the humans that can’t make it without electronics. Thanks to the ingenuity of people, there are robots of every size and shape available in the robot army, and it’s easy enough for them to start producing still more robots, including kinds that don’t exist in the real world yet.
So that’s where we start:
Monster Power Level and examples
I: Tiny, mostly harmless service robots like vacuum cleaners or checkout machines
II: Human-size robots that aren’t built for combat — a manufacturing arm or a translator
III: The classic security robot that moves and acts like an ordinary human with a gun
IV: An advanced security robot, bigger, tougher, and more maneuverable — maybe with wheels, treads or spider-type legs
V: A robot transport, which provides cover fire before it drops off a load of killer robots
VI: A self-driving vehicle — one bristling with weapons, like a tank or fighter jet
Characters in this setting are action-oriented; they have their highest stats in Action (if they’re the gun-toting soldier kind) or Wits (if they’re the genius programmer that turns the robots against themselves kind). Ego is less important in this genre, though a typical adventure probably has at least one opportunity for a hero to pretend he’s a robot to get through a dangerous situation, or to talk another group of survivors into joining forces.
Think of Specialisms that offer skills: Robot Programming, Discipline, Driving, Stealth. And make sure your character isn’t a generic hard-bitten warrior with personality traits like Practical Joker, Silent And Deadly, or Master Negotiator.
