Can someone please help me....new to Splinter Cell and I'm stuck in the lobby of the South Wing. I knocked out the guards, I used the Colonel to do the retinal scanner and open up that door in the back of the lobby. And here's the problem....once I get in that empty room, I shoot the camera above the double doors, but when I open them, the alarm goes off. The objective is to "mike the glass elevator". Is this the elevator?? How do I stop that alarm?? HELP HELP HELP ahrrrrrrr.....
