As they continued their way through the brush and heavily wooded area, they get to a clearing where the sky above them is covered by the branches of trees, obscuring the rather rocky space under them. The man in the labcoat turns to the other two men, and they nod in agreement again. They both approached the large boulder next to the bespectacled man. Patting the rock, they pause, both of them reach into their jackets and pull out matching flashlight like devices. Activating them, a beam of light flashes out of the tube, illuminating the darkness with a low green glow, revealing a keypad each where they stood. The two goons push the holographic buttons, both sides having a separate six digit passcode, but they were successful on input.
The boulder is then pushed back by unseen rollers, a set of stairs leading down revealing itself. The men place their devices in their coats again and follow ''Metallica'' down the metal stairway leading into the darkness below.
