Escape from the Planet of the Robot Monsters is an arcade game developed by Atari Games in 1989. The game is based loosely around the campy science fiction B movies of the 1950s. It was ported for most major home computer platforms of the time. According to the introduction, Planet X is a synthetic industrial planetoid whose most notable feature is the research laboratory of the buxom and brainy Dr. Sarah Bellum. Evil aliens called Reptilons invade the planet, capture the good doctor, and force the rest of the humans to manufacture a robot army to take over the Earth.
