Secrets

 * 1) In the area past the steps past the blue door, open the wall with the blood pool in front of it to get a soul sphere. (sector 679)
 * 2) Take the curved staircase at the southwest end to a room with a computer at the north end. Use the wall with red lights to get a berserk pack. (sector 397)
 * 3) In the jagged caves at the west end of the map, enter the center of the lava to get a megasphere. (sector 403)
 * 4) In the cargo room at the north end of the map, climb the crates at the southeast up to a megaarmor. (sector 481)
 * 5) From the previous secret, drop west to a health bonus to lower a crate with a computer area map. The crate with the health bonus counts as the secret. (sector 486)
 * 6) In the blue-floored hall, take the lift up to the ledge with several switches. The switch northwest of the lift opens up an NFG and mini-batteries. (sector 515)
 * 7) Take the long corridor at the north end of the map east and south, all the way back to the teleporter to the yellow key room. One of the curved steps is the secret. (sector 121)
