I get all the way to the room where the contact is, I hear him groan inside but when I go in the room he's not there. I go out the door on the right but he's not there either. I go into the room with smoke and shoot out the skylight and cross the room to the door but it won't open. Has anyone else seen this and what would be the solution?

If I understood correctly, you should see the contact lying on the ground<--(Use your Night Vision)...and the door should be open.

The contact is on the ground in the room w/the fire. When you enter the room from the hallway, he'll be sort of to the left and close to the fire. A little tough to see at first, but you'll see him. Once you see and talk to him, you'll be able to open that door in the smoke filled room and continue on.
