Umbra is a PWAD for Doom II and a MBF21-compatible source port. It was designed by rd and was initially released on October 14, 2024 on the Doomworld forums. It features a very large map, and also includes an outro map on the MAP02 slot ("Time") and a short bonus map on the MAP33 slot ("Typical Circlestrafe Fight"), which contains an outtake fight.

Umbra was chosen as one of the winners at the 2024 Cacowards.

Umbra uses the following music tracks:

• "Guardian Angel Loses Their Will" by em essex (msx2plus) for the level itself;
• "Undersea" by Sarah Mancuso (esselfortium) for the intermission screen;
• Custom MIDI by rd for the ending level.

Walkthrough

Map of Umbra

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.

Secrets

1. At the west side of the main area, take a large lift up to a super shotgun, then head south, through a break in the fence, to a small area with some rubble on the south wall. Climb this rubble and jump east to the opening, getting armor bonuses, boxes of rockets, rockets, and a soul sphere. (sector 422)
2. In the hall northeast of the area with the yellow key, open the purple door, flip the switch for the lift and open the red and blue bars to get to the lift. Ride it up and take the teleporter to the secret pyramid area where you can get energy cell packs, energy cells, soul spheres, a BFG9000, rockets, and medikits in the initial area. More ammo and a BFG9000 can be accessed in the hall after the switch is pressed. (sector 880)
3. In the hall northeast of the area with the yellow key, head northwest to the terminal on the edge. Look in that direction and slightly to the right of the terminal to see a switch in the distance, just to the left of the brighter section. Shoot it and run back to get the energy cell pack. If you keep going, there will be a backpack. (sector 2009)
4. At the first hub with two ice mounds below you, head northeast. A compartment to the west that opens has former humans and armor bonuses. To the left of the computer in this compartment is a hidden switch. Press it, then quickly run north all the way, behind crates, a ship, and behind a stack of black crates to a rocket, which is on a tall lift. Ride up, jump east to another black crate, then east again. Climb up and fall into a crate to get energy cells, stimpacks, and energy cell packs. The switch in here will also open the cage to the north which contains rockets and boxes of rockets. (sector 2832)
5. At the southeast end are two thin paths over the sludge that slows you down, one path being at ground level and one being high up. Go north to the two switches, flip them both (the north one in particular), then quickly run south across the thin path to the block between the paths, which will lower. Ride up, take the other path, and go across platforms going northeast. Press the switch where the backpacks are and head west and north to find armor bonuses and a teleporter. The teleporter takes you to the black key area. (sector 4364)
6. In the area located at the southeast part of the map, head to the south balcony, go to the east side, and look north. Shoot the switch on the wall, then quickly run west, north up the steps, and north to a room with energy cells and a plasma gun. (sector 4646)
7. In the large area with the blue tower near the south side, go through a break in the fence to the west. Head west, climb the rocks, go behind the tree, get shotgun shells, armor bonuses, and rockets, then jump west onto a block. Head south all the way through this cave system to find rockets, shotgun shells, and a backpack. (sector 4683)
8. At the north end with the deadly void, go to the north switch and enter the teleporter. Jump southeast, climb the green steps, walk west, then run and jump northeast to the other side. Keep climbing up and to the health bonuses on the ice. Jump north towards the rockets and use the east wall to find a secret area with medikits, a green armor, and a backpack. (sector 4869)
9. In the northwest lava caves, go southwest from the central rock with lavafalls around it. At the fence, look for a button in the distance and shoot it. Head north and west to get a box of rockets, rockets, health bonuses, and a megaarmor. (sector 5336)
10. At the west side with the platforms above the deadly void, go to the center, which is a ledge with two armor bonuses just southeast of one with a large tree. Use the brown wall here to uncover a switch. Flip it, then quickly run west across three platforms, up the steps to the west, then south and southeast through a lift, getting there just before it closes. This grotto has health and armor bonuses. (sector 5864)
11. In the waterfall caves west of the center, go north and down as much as you can, then through a waterfall to the west. Use the blue candle to unlock the west wall here which has armor bonuses and rockets. (sector 6173)
12. Start going up the north steps from Secret #11 and at the third step, use the west wall for a new passage. Drop off into the new area and flip the switch to the north to access a room with shotguns, medikits, rockets, armor bonuses, energy cells, and a megaarmor. In the alcove with rockets, use the west wall and the switch behind it to unlock a compartment to the southwest with more rockets, boxes of rockets, and a switch. (sector 7914)
13. Go to the teleporter that leads you out of Secret #2. Instead of entering it, use the switch to the north. Go northwest to a teleporter leading to the secret rest area. The secret bullet waster can be acquired here. (sector 8165)
14. In the northeast area with all the medikits near a computer, below the computer are three pieces of paper. Pick up all of them, go back to the computer, and there will be another paper allowing you to get on the computer. Jump southwest to the crate containing rockets and a box of rockets. (sector 8260)
15. Head south from Secret #12 and in the next room, flip the northwest switch and go through the passage. Press the switch to the north, take the lift up, get on the higher rocks, and go to the corpse. Use the metal wall behind it, then run east and south into a small alcove with a soul sphere. (sector 9268)
16. Near the entrance of Secret #11, shoot a switch near the east side. Head inside Secret #11 and use the switch at the west side. Get out of there, climb up two rock steps, jump across the pillar to the north end where the switch is (the switch raised the pillar). Head north to the other side and immediately west, past the wooden wall, making it in the ten seconds since pressing the switch in Secret #11. Climb up and take the teleporter to enter the area where you will get the purple key. (sector 10246)

Bugs

A teleport landing (thing 7237) has no flags set for any of the three difficulty classes, so it does not actually appear in the level.
