The Laser Pen is an ordinary looking pen with a very special and cool function: it can cut through metal! You will use this pen to cut the grate roof on the top Toupee Terrace to save one of your fellow secret agents.
How to Get the Laser Pen
Go to the docks area, and make your way up to the top onto the roof. Use your chameleon suit to avoid the guards by standing still. Run across the roof until you reach a small doorway. Then go inside. Head down through the floors in this room the same way. You can avoid the dogs whenever you stand still. When you get to the bottom-left corner of the room, you can drop down an opening into a smaller room. One of your fellow secret agents is lying on the floor, tied up with rope. Click on him to set him free and he’ll give you a laser pen.
