Highway Acceleroid Booster is a GZDoom gameplay mod where you play as a robot girl that's part car and part super fighting robot. Armed primarily with mobility, a series of battle chips for extra combat data, and a variety of utensils installed into her gauntlets, she zips from place to place to gather additional combat data. And to help out wherever she's needed, admittedly. Helping feels nice. Inspired by Mega Man X, gameplay feel is a little bit more cartoony and high-tech than usual, with some pretty outlandish weapons doing some silly functions.. Designed to act as a complement for sci-fi/space-age mapsets, the gameplay mod acts as a direct contrast with High Noon Drifter. Rather than being very simple and low-tech, this mod is a little bit more complicated and hi-tech. If you've been looking for a mod where you can play as a robot, android, gynoid, or you've been looking for something to compliment Stardate 20X7, this might be up your alley.

SuperDoom is a mod for Doom II that aims to recreate SuperHot's gameplay in Doom.

Project Einherjar is a five-episode total conversion for GZDoom/Doom II developed and released by Mike MacDee (Impie) in the summer of 2016; Episode 2 was later released in the winter of 2016; and Episodes 3 through 5 throughout early 2017. It is set during nuclear winter, and features 35 new maps and a totally replaced roster of weapons and enemies in the style of an early-90s 3D shooter. Impie made the mod as a promotional gimmick for a dystopian novel series set in the same universe. The gameplay involves lots of fast, brutal shootouts with enemies that die relatively easily, but can badly injure the careless player. Each episode features a short story that sets the stage for the action to follow, written in the novel's pulpy style. The mod series is referred to as "Winter Agent Juno." Impie got the mod series title from a Japanese review blog's description of the mod: "Winter Agent Jin: Destroy the Armored Sisters Institute!". Impie later released a fan mod of the Wolfendoom episode Operation: Arctic Wolf using Project Einherjar assets. An 11-map sequel episode, Midgard Outlaw, was released in 2018. The third Winter Agent Juno mod, Operation Sea Wolf, was released in 2019.

Add bands of mutant cannibals, limited ammunition, and a mysterious group of gas-mask wearing para-military types prowling the rubble.

The 'Master Levels for Doom II' is a grab-bag collection of various unstructured, unorganized WAD files, all made by various map authors with a wide variety of styles and design conventions. Most of the authors involved in the project, made these maps with the intention of them being a part of larger episode or campaign overarching a certain theme even before being contacted by id Software for this project of theirs. However, not all maps made by these authors were accepted by id Software, being later released freely by their creators after the fact, with some of them even continuing their work further, beyond the original submitted level sets. The Masterpack works by taking everything made by the authors past, present and future to the original Master Levels release and bringing it together in a single WAD file for your enjoyment. All 45 relevant (plus 1 bonus) map are now fully playable as 5 separate, organized episodes. And with this, you can now properly enjoy the works of Doom's early great authors, some of early Doom's most timeless work.
