Guard Robot
From KeenWiki
Guard Robots are purple robots used in the Vorticon Mothership to protect different areas.
They are basically hovering machine guns, possessing two powerful arm-mounted lasers that can kill intruders instantly. They are also deadly to the touch, making them very difficult to pass. Their dangerous abilities are to make up for their lack of intelligence; they simply float back and forth, turning when they reach a wall, and firing at random intervals.
They are immortal, or at least cannot be killed with the Vorticon HyperPistol. They were probably built by the Grand Intellect to serve as a primary security measure, and in order to protect the Mothership at times when the Vorticons were busy with other tasks.
