The UAC's experiments with terraforming, teleportation and energy weapons had long been of interest to various rival companies, but they refused any cooperation offers due to the sensitive nature of their resarch. It was only a matter of time before someone wormed their way into their workforce to see how the UAC ticked. One such rival is Yoshikatsu Heavy Industries, specializing in bionics, industrial machinery, aerospace research and pharmaceutics. You've worked for them for a while, and they selected you to try and sneak your way into the UAC by posing as a maintenance technician. Surprisingly, you were able to get in without much issue - they weren't even fazed by you hanging around board meetings on occasion, nor did they notice you kept tabs on the factory floor whenever you passed by. You're sure they didn't even bother looking into misplaced schematics, because you did as told and shredded sensitive data. Of course, you took a good look at it first thanks to your cyber eyes. Things were going quite well until the facility you were at went into lockdown - no briefing, no coordination. Everyone quick enough to leave must have escaped, but everyone else? They're likely dead, given the place looked like a charnel house. Except no one bothered informing the lowly pawns keeping the place running, which includes you. With much more at stake than technical data, you retrieve the one weapon you brought along and decide it's time to bail. Good luck, agent Ayumu.

Dead Sea Scrolls is a vanilla compatible (comp -3) episode replacement for Ultimate Doom. The "story" is a schlocky adventure with the real life mystery of the Dead Sea Scrolls and Abrahamic mythology sprinkled on top. Emphasis is on varied, approachable gameplay with anything from puzzle, stealth, horror, to light slaughter.

Neptunian Nightmare is a vanilla mapset and partial conversion for The Ultimate Doom (-complevel 3). It's an atmospheric romp heavily inspired by the Doom Bible and its associated prototypes, as well as Team TNT's TNT: Evilution and Icarus: Alien Vanguard.

Shadows is a very personal tribute to Death Bear's mapping origins and the journey they've been on the last four years.

Each of the episodes follow similar themes as the original, with some personal flavor and some added twists.

Nostalgia Zero is a set of 36 maps in CL3 for The Ultimate Doom. This WAD uses exclusively vanilla textures and vanilla limits, with the target source port being Chocolate Doom. In terms of gameplay and level design it’s much closer to the IWAD than either of the Nostalgia WADs, though it does sometimes dip it’s toes into more modern tropes.

Cramunhão is a tribute to John Romero's Sigil. It replaces the 4th episode of The Ultimate Doom. Inspired by the works of John Romero on Sigil, it started out as a single maps contest emulating the mechanics of Sigil, but ended up evolving into a full episode community project. It has contributions from well known mappers such as Daniel (NeoDoom, Final NeoDoom) and Deadwing (Ozonia, Moonblood), just as newcomers like Sca, who has made his first map ever for this mod (and also one inspired in the hospital his first son was born, at that very day).

"Le Gars Qui A Fait Doom" Level Collection is a series of 8 new Ultimate Doom maps for Limit Removing ports. They come in all styles and colors, and all of them are more or less inspired by John Romero, whether it's his old IWad maps, his modern offerings (SIGIL and its sequel), his other games, or even his real life. You can play each of these maps in any order you fancy, as there's no clear theme or difficulty order. Each wad can be played standalone, à la Master Levels, and some of them contain new textures and resources.

A map with the general theme of quake areas mixed with some sand areas

The project was designed to be a creative exercise in building levels around the original map titles for all 36 maps of the Ultimate Doom with an increasing emphasis on creating challenging but enjoyable maps that will even given experienced veterans a stern test (Especially for an Ultimate Doom megawad and especially so for episodes 3 and 4). All maps are built to a limit removing (complevel 3) format and are beatable from a pistol start, difficulty setting are included, but some may need a little refinement to pitch the difficulty with more precision. Co-op starts are included but anything beyond this will be patchy and dependent on the author who made the map.

Classic E1 replacement

This is a Boom compatible megawad replacement for The Ultimate Doom. It features 4 episodes with 9 levels each all themed in the vein of the original game.

A community made Episode 4 replacement for Ultimate Doom, sequel of the highly acclaimed and cacoward runner-up Deadly Standards episodic series. This time the classic stock assets theme got a rough deviation to more new assets, taken mostly from Alpha Doom and Romero dump of unused assets, as well as some other sources like Doomer Boards: Earth Ends and Ghostbusters Doom. Fight a terrifying world of a hell (on Earth?) that you never experienced before! Behold, the horrors of bureaucracy in a corporate world where anonymous towns are dominated by brutalism!

Experimental mod for Ultimate Doom. Doomguy has dementia. The Thing you can’t Defeat lets you replay the first episode of Ultimate Doom as it slowly morphs into a confusing and demented nightmare.
