Medal of Honor: Frontline

After passing through the speech stage area, you’ll enter a series of lavishly furnished rooms. Look on the walls of every room and you’ll find no less than 2-3 clocks on the walls. The document you need for the mission objective is in a room with a pool table, behind one of the clocks. There are also more clocks on shelves and walls as you continue further into the level. Shoot all of them until the trophy unlocks.
