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.

This mod builds on the PSX Doom Total Conversion and Doom 64 Retribution, to take advantage of the latest GZDoom versions and adds many features that make them more faithful but were impossible to implement at their time of release. To achieve this, a large amount of the code has been adapted from GEC Master Edition (also known as DZDoom) into ZScript, while looking at the reverse engineered source code and existing source ports of these games for reference. In addition to that, the mod is highly modular and also incluides many optional "enhancements" that deviate from the original experience. Depending on your taste you can opt for going as close to vanilla as possible, or experiment and play with upscaled textures, PBR materials, flashy particle effects and other features that are common in other GZDoom "enhacement" mods.

Ashes is a Post-apocalypse themed Doom II Total conversion, designed to be run in the Gzdoom or Qzdoom ports, and includes support for either software or hardware options.

Add bands of mutant cannibals, limited ammunition, and a mysterious group of gas-mask wearing para-military types prowling the rubble. Heavily inspired by 90's FPS games, 80's post-apocalyptic movies, and a shit-ton of other references, Ashes will be designed to either run as a weapons mod, a map-pack, or as a full conversion, depending on the modules downloaded and run.
