U punch the switches to break them and be sure to dodge that electrical shock thing that happens everynow and then. That barrier surrounding the generator has a different pattern everytime u break the switch so just watch it and know the patter. To move fast from swith to swith use the charged foward jump.(If u have PS2 charge your jump with x and hold sprint(L2) and run, foward and release and he jumps really far and fast. be sure that your going around thhe room in a circle.
