MAP15: The Vault (Hellbound)

Secrets

 * 1) Drop down at the start and enter the lower passages. Go until you see a brightly lit area to the north. To the south of that, open the green wall in the southwest corner for a super shotgun. (sector 66)
 * 2) In the easternmost room with the two lifts, ride the first one up and look south. Shoot the switch, then jump to the ledge on the east side. Go into the room for a megaarmor, a chaingun, a backpack, a box of ammo, and a switch. The switch will open up the alcove with the red key in one of the hallways in the center of the map, which is required for reaching the secret exit. (sector 434)
 * 3) Head south into the hall with the rising and lowering chaingunner blocks. Head to the east end of the hallway, and use the step to go over the railing. Head around for a stimpack and a partial invisibility. (sector 553)
 * 4) Enter the southernmost room requiring the blue key. Quickly go up the steps and head around to spot a button. Shoot it, and on the inner bend another button will show up. Do not go down the steps, or this button will be closed off. Press this button, then quickly go around to where the previous button was and look at the opposite wall for a third button. Quickly push this, then run west through the opening for the secret. Go all the way through to the switch, which will open the way to the secret exit. (sector 1023)
 * 5) In the southwest hallway with the monsters behind cages, enter the control room and press the right switch. This releases the monsters, but also opens up an alcove containing an invulnerability nearby. (sector 1685)
