Robots are sentient and, as usual, that's not good for humanity. Shoot the robots and rescue the humans.

Because of your unique ability to resist their brainwashing, you are the only person who can save humanity from the Robotrons. You must rescue as many human families as you can while taking out as many Robotrons as possible. Robotrons come in all varieties from the Grunts (the less than brilliant guys looking to smash you) to the Brain Robots (who can brainwash humans and turn them into enemy Progs).
