I am on the level where you are Chase Edmunds, a federal agent that is undercover working one of the biggest terrorists Peter Madsen. I followed all the instructions after I killed on the bad guys from the water tower with my sniper rifle.
Then it says go back to the main building and protect Madsen from getting killed when the bad guys use an armored truck to smash through the main building. After I had killed all the bad guys in the MAIN BUILDING I do not know what to do.
My PDA does not even have the objective: Enter the Main Building checked off next to it. All the bad guys are dead and I am stuck in the main building with Madsen and his men.
I can get any of the doors open. I am stuck and waited and tried to do everything but I don't know what to do next. What do I do next?
