MAP15: The Prisoner (NOVA: The Birth)

Secrets

 * 1) In the hallway with prison cells, go to the door on the left side, then open the wall to the north, finding a backpack and a shotgun. (sector 32)
 * 2) Enter the big room with the blue key from the south door. Approach the main part of the room and a lift lowers, which is to your right. The lift concealed a switch, and using this switch lowers another lift, this time at the southwest end. Quickly enter this opening for a megaarmor and a super shotgun. (sector 167)
 * 3) At the red key courtyard, go to the southeast corner and spot a switch tucked near the bottom of the building. Using it lowers a teleporter at the south end briefly. Take it to appear at the top of the nukage fountain, where you will get a berserk pack. (sector 297)
 * 4) Take the door east of the blue key and make your way to the end. At the bottom, open the wall at the northeast corner to get a soul sphere along with one of three switches required to lower the barriers to the secret exit. (sector 331)
 * 5) In the room with the cyberdemon that warps out of the cage, go to the southeast corner and use it to reveal a switch. Flip the switch so you can get the computer area map in the northeast corner. Note that the switch will also lower one of three barricades leading to the secret exit. (sector 349)
 * 6) Three barriers block the way to the secret exit. Two of them are in Secret #4 and Secret #5. The final switch needed is actually directly behind the normal exit switch. Now that the three barriers have been lowered, enter the passage leading east from the room before the exit room to the secret exit. (sector 374)
