Secrets

 * 1) In the southwestern corner of the map is a pool of blood with a switch in it. Flipping this switch opens the large octagonal structure in the area to the north. Inside the structure is a pentagram with a soul sphere on it that counts as a secret.
 * 2) Directly to the southeast of the aforementioned pentagram structure is a vaguely hexagonal green marble structure. Walk around the back of this structure and two of its walls will open, revealing a secret area.
 * 3) In the northeastern corner of the map is a maze of blood-filled tunnels. From its start, head right, right, left, then right. You'll end up at a secret platform with a BFG.
 * 4) After flipping the switch next to the red skull key in the blood maze, return to the central area after taking one of the teleporters in the maze. Go through the southern of the two blue doors in the east. In a nearby alcove is a switch; press it to lower a wall back outside. Flip a second switch behind the newly lowered wall to raise a bridge to the "teleport tube" in the southeastern corner of this room. Go through that teleport to be taken to a secret area.
