Renegade Robots

Sometimes, robots in Mega-City One manage to break their own programming, but it is normally done by criminals or technicians with a grudge.  These robots can escape their former masters, and take up hiding within the darkest areas of the city, such as disused or irradiated sectors, or even the Undercity.  Her, they meet up with other escaped robots, and may form a force intent on building its own criminal empire and bringing terror to all the squashy pink beings that forced them into servitude.

A renegade robot force has access to a wide range of different units, allowing you to tailor them to the enemies you are likely to face. The downside is that they can be very expensive to recruit.
