E1M7: Forfeited Salvation (referred to internally as MAP07) is the seventh and final map in episode The Vulcan Abyss of Legacy of Rust. It was designed by Samuel Villarreal (Kaiser) and uses the music track "Tactical Blasphemy" by Xaser Acheron. It is a wooden complex centered around a large "O", guarded by a cyberdemon and shocktroopers. On Hey, Not Too Rough (HNTR) skill level or below, the cyberdemon at the map's center is the first the player encounters in the expansion.

Map of Forfeited Salvation

Letters in italics refer to marked spots on the map. Sector, thing, and linedef numbers in boldface are secrets which count toward the end-of-level tally.

Essentials

You begin inside the O, with the cyberdemon facing away from you. Step forward to drop down to a super shotgun, rocket launcher and incinerator, then head east until you leave the O and reach a door with red torches. Go through the door and climb some steps, kill any zombies waiting at the top, then press the skull switch at the north end of the room; this will open the west wall to reveal a teleporter, but will also open the block behind you and release imps (plus demons and shotgun guys on Hurt Me Plenty (HMP) skill level or higher). Enter the teleporter to go to a ledge above the starting point, collect the calamity blade here, then press the eye switch to raise lifts around the cyberdemon's platform. Kill the cyberdemon if you have not already done so, then get on top of its platform to get the red skull key. Taking the key releases banshees from the north and south ends of the map.

Open the red door on the west side of the O to confront some demons, shocktroopers, and zombies, then head north through the next room to find the blue skull key at the top of some steps. Go back to the O, killing a mindweaver blocking your way back to the red door, then open the blue door on the east side to face more shocktroopers along with cacodemons and one or two vassagos. Climb the steps to the east end of the room, and prepare to kill any monsters hiding behind the east wall (some of them will teleport to the previous room), collect the supercharge that the monsters were guarding, then press the eye switch opposite to open a red teleporter. Enter the teleporter then walk south along a ledge to enter a room with imps and chaingunners, then press the eye switch at the south end of the room to open a skull switch by the blood pool behind you. Press the skull switch to open the mouth of the nearby skull, which will spit out the yellow skull key.

Go outside the O and open the yellow door at the south end of the map, then climb the steps to find a caged mindweaver guarding a skull switch, which you can press to open the south door and release one or two vassagos (plus shocktroopers on HMP and an arch-vile on Ultra-Violence and Nightmare). The exit switch in this room is a trap and will drop you into a lava pool with more vassagos—the level will automatically end when your health reaches 1%.

Other points of interest

Run off the north side of the O to reach a supercharge, then step east to land on a ledge below with a megaarmor.

Compared to other official levels with death exits using sector type 11 (such as Doom's E1M8: Phobos Anomaly, or Plutonia's MAP11: Hunted), the enemies in the final room can easily be killed by simply saving one of the two invulnerability pickups and collecting it just before pressing the false exit switch; sector type 11 only nullifies invulnerability given with the iddqd cheat code, not that of the power-up.

Secrets

1. Leave the O and go to the south-west corner of the map to find a tunnel with an invulnerability, as well as a teleporter that goes back to the starting point. (sector 269) Watch out for the banshee that ambushes you as you collect the powerup.
2. Go outside the O and go to the block with bleeding skulls in the south-east corner of the map, then press the skull switch on the east side of the block to lower a pillar with a partial invisibility. (sector 105)
3. After raising the bridges inside the O, go to the north-east corner of the O and run to the teleporter you used earlier to get to the calamity blade. You will teleport to a megasphere. (sector 273)
4. In the room with the yellow key, step through the southernmost window to reach a narrow ledge below. Carefully walk to the end of the ledge and open the wall here to enter a small cavern with "I <3 MY MOM" on the floor. (sector 361) The cavern holds weapons, a megasphere, a partial invisibility, an invulnerability and four fuel tanks.

Bugs

The button to raise the bridges to the red key also targets the corner bridges (tag 2). These corner bridges consist of multiple sectors of different heights; if one of the other switches (linedefs 773, 777) targeting the corner bridges is pressed first, and the red key bridge button is then pressed as soon as possible, only one sector of the corner bridges gets raised, revealing untextured sides and halls of mirrors. This must be done in multiplayer co-op because the bug is time-sensitive and the buttons are too far apart.

Inspiration and development

The resemblance to MAP11 was a complete coincidence, according to Xaser, who was "aiming more for a Plutonia vibe".
