The one that starts you off with the water and two robots? While in the water use WASD to control the water robots so they are on the pressure plates. then go to the nearby light and robot. have the robot with the magnet feet go next to the closed door. there should be a higher up light there. travel through and spam down so you open the second door. then bolt up and into the robot and walk through the doors. go onto the highest ceilng and walk to the right until you see the exit outlet.
