During level 8, "An Innocent Life", one save point is within a room with three or four robots, deadly green ooze below, and large sparking arcs of electricity that you must avoid to get to the other side. From the save point, run up the stairs and take care of the robot up there. After that, hop down at the outcropping to the Terminal below. You should have just avoided the first half of the first arc of electricity. After dropping down, the robot guarding the terminal to temporarily shut down the arcs of electricity will not usually "see" you, since you arrived the wrong way. He now should be an easy kill.
