James Bond 007: Everything or Nothing

On the game James Bond Everything or Nothing on the level deep decent I have a question. when you first start you are on this platform but, when you get a q-spider and go back the oppisite way you are standing if you do not move the q-spider can go under the railing and oround and ontop of these obstacles you come upon a door just so the spider can get through and a guy in that room after e opens the secret room door there is all these vests and batteries and every thing how does bond get in that room him self?
