From The TimeSplitters Wiki

ChassisBot has only appeared in Timesplitters 2, where it was a basic enemy in the Robot Factory level. Chassisbot, like most robots, is stunned when shot by the electrotool. He is a slender robot, much like Gretel. In Robot Factory, most ChassisBots carry scifi handguns. It is a servant for The Machinist, made from various pieces of scrap metal collected in the factory.
