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 the three models of Gretel and would appear to be an incomplete SentryBot model. In the Robot Factory level, most ChassisBots carry Sci-fi Handguns. It is a servant for The Machinist, made from various pieces of scrap metal collected in the factory.

ChassisBots have a pathetic one star Default AI in Arcade Custom mode. They have weak atributes, though because they are slender they are somewhat difficult to hit. They are of average height.
