Blue Pass Card
The Blue Pass Card is found in a small hole in one side a huge sloped room. Lara jumps from atop some catwalk to the area above the Pass Card, and slides into the small hole. Once found, Lara takes the obvious tunnel back to the catwalk above, and utilize the Pass Card in the blue slot at one end of the metal pathway. Beyond lies the Perimeter Hallway and a new, more powerful enemy, the Flamethrower Guy.
