oh, its really simple, actually.you, oh how do i describe this? in the huge room with all of the guys that keep teleporting in, you look up and see conveyor belts. you jump on to them. at the end of one of them there is a small hole-looking things. it is actually a small vent. send a spider-bot down through it and make it press the little button thing. now you should be able to get through the force field!
