Hello all, I'm new to the board!! I am currently playing the stealth misssion in egypt (stop the nuke from blowing up), the one to find the EX-base commander. I have killed everyone without getting detected visually and no alarms. The mission objective is to infiltrate unoticed. I have done so with great efficency, goto love Shade. There are a few items to manipulate, the generator for the alarm. and a few buttons in two guard rooms. There is also a ventilation passage that seems industructable. I need help. The mission objective will not complete and the doors and ladders are inaccecable. Any help would definately be appreciated.
