MAP09: Vesperas (Master Levels)

Vesperas is a map that is part of the Master Levels for Doom II. It was designed by John Anderson (Dr. Sleep), and is contained in the file VESPERAS.WAD. In the PlayStation Final Doom port it is the last level of the Master Levels episode and uses the music track "Sanity's edge". Completing the PSX version leads to MAP14, the first map of TNT: Evilution, with all weapons and game status retained.

Yellow key
In the starting area, use any of the three doors. The western one offers the fastest route. Use either of the two western lifts. Get to the west side either through the central room or along the corridor. The bars open automatically. Step out a bit to the nukage pool to open alcoves both in the north and the south. There is a narrow and invisible ledge that runs from the east side to the southern alcove. Go to the alcove and press the button before you (it will be highlighted as you approach). Grab the yellow key.

Red key
The key lies at the northwestern room. Leave the nukage pool area and go to the north side where there are yellow bars. Open them. Go to the eastern room, and a lift will lower. When you go down, press the switch at the southern alcove. The wall at the west will open. Grab the red key.

Blue key
Go to the east. Walk down the staircase and up the other. The gargoyle button to the left requires the red key, so you can press the button. Drop down, turn around and press the button to lower the stand with the blue keycard. If you grab the key from the south, bars will rise as if blocking your way. Merely go around them and use the lift to get back.

Exit
Return to the beginning area and press the switch indicated by blue lights. Beware and kill the revenant and press the exit switch for the end.

Secrets

 * 1) In the nukage pool, walk through the nukage fall and there to a teleporter. (sector 169) The teleporter leads to a room with a medikit.
 * 2) In the southern alcove of the nukage pool area, the closet that contains the yellow key (sector 267) counts as a secret and is impossible to miss because the yellow key is required in this level.

Differences between PlayStation and PC versions

 * The nukage pool (B) has brown slime instead of green nukage.
 * In the same area (B), the teleporter to get out of the pool is placed at the west and not at the east.
 * In the same area (B), the middle textures of the ledge were removed. This makes the ledge more noticeable and evident that the player should make their way to the southern alcove.
 * The central south area, the red key room and the blue key room all have two inaccessible alcoves that contain teleporting monsters. In the PlayStation version, each area only has a single alcove.
