Secrets

 * 1) At the far end of the first "L"-shaped hallway is a wall with blue triangles on it (just right of the second window with moving shutters). Open this wall to access the areas behind the shutter windows.
 * 2) Just before the platform where the blue keycard is found is an area with a seemingly inescapable pool of brown sludge. In fact, there is a misaligned texture on the northern wall of the pit that can be opened to get out. Inside is a super shotgun and ammo.
 * 3) From the crate the red keycard is resting on, drop down to the left. There is a secret teleport that takes you to an area earlier in the level.
