Remnant

Remnant is a single-level PWAD for Doom II with a limit removing source port that was released in November 2019. It was created by Aurelius and uses the music track "Corrupt, doomed" by Teemu "Forchion" Mastovaara. Remnant was awarded one of the Cacowards in 2019.

The PWAD includes relevant parts of the OTEX texture pack by Ola Björling (ukiro), sprite replacements for some objects, and a DEHACKED lump specifying two custom monsters:
 * the Cardinal with 5000 hit points, replacing the spiderdemon;
 * the Master with 6000 hit points, replacing Wolfenstein SS.

Secrets

 * 1) Approach the door north of the starting cage to have bars appear in front of you. Go back to the south end of the room and up the steps. On the walls, you will notice one of them is brown instead of gray. Use this wall to find a switch, which will lower a lift to the northeast. Press it and quickly head to the east ledge, then go north and up the lift before it rises. Follow the trail of armor bonuses to the soul sphere. (sector 707)
 * 2) In the large round room at the west end of the map, head up the north steps and go just to the right of the hall that leads outside. Look towards the left wall to find a skull. Shoot it to lower the megaarmor further to the west. (sector 3192)
 * 3) Climb up the steps to the west of that round room until you reach the ruined wall. Jump off to the east, facing the column with the skull on it, and you should drop to a rocket launcher. (sector 5152)
 * 4) When you finish with the inside of the small castle that had the berserk pack and invulnerability, head north towards the teleporter, but instead of taking it, look to the west and jump to the water. Then go south towards the chaingun, box of ammo, and armor bonuses. (sector 1942)
 * 5) After opening up the area east of the round room, go to the northeast corner and through the grove you will find a teleporter taking you to a megasphere. (sector 3742)
 * 6) Now head east from that area back outside and head just south of there, then go west through the trees. You will find a megaarmor and health bonuses here. Remember this area for later on as you will have to reach another secret after finding several hidden switches. (sector 128)
 * 7) In the same outside area as above, fall to the lower water below and go south as far as you can. You should find a platform with rockets, a backpack, and a teleporter leading back. (sector 6869)
 * 8) When you cross the bridge to the door that leads to the red key room, note the red pads south of the door. Go to the south side of these pads and cross over them, then quickly run back east and through the windows to the east before the fences rise. Out here you will find the area map scroll. (sector 1116)
 * 9) Head into the water south of where the blue key is and outside of the stairwell. Head south and west where you see a health bonus and through the small path you will find a medikit and an energy cell pack. (sector 958)
 * 10) You will need to find four purple sigils in order to find this secret. The first is in an outdoor courtyard at the northwest end (mentioned in Secret #2), tucked at the far end behind trees and rocks. The next is a shootable switch with a green torch in front of it, to the south of where the round room is. Climb the ruined wall to get a position where you can shoot it. The third is a shootable switch accessible from the small castle at the southwest end, where when you head through the teleporter to the upper levels, go to the northeast section and jump from platform to platform that has the red circles on them, until you reach the one with the statue on the pillar. From there, look south and shoot the switch. The fourth and final sigil is located at the east end, a bit south of one of the four blue sigils for the blue key. Go towards the rockets near the rocks at the eastern fence and head southeast to find this sigil, then shoot it. Once you have found all four sigils, return to Secret #6 and at the bottom, the switch at the west end will be accessible. Pressing it removes the bars to the nearby teleporter. When you teleporter, head up to find an arch-vile and a BFG9000. (sector 939)
