What Doom Mods and Tools Does JP LeBreton Offer?

Updated

JP LeBreton's itch.io page groups his Doom-related work into three broad kinds: gameplay mods that change how you play (KEYMASTER, Green Demon Challenge, Phobos Minute, Always Pistol Start), utility tools that change how your game files are organized or searched (WadSmoosh, JP's Secret Finder), and HUD/stat add-ons that change what you see on screen (JP's HUD, Run Stat Tracker). There is also one content release, Works of the Masters, a Deluxe Edition of the Master Levels for Doom II. Most of the gameplay and interface items are built for UZDoom, so check that source port before installing.

Gameplay mods

These change rules, loadouts, or level behavior rather than adding new maps.

Mod What it does
KEYMASTER A gameplay mod for UZDoom
Green Demon Challenge A challenge mod for UZDoom where "your only escape is the level exit"
Phobos Minute A UZDoom mod described as "a classic twist on the speedrun"
Always Pistol Start Starts every level with the default loadout
The Marked (prototype) A no-weapons monster manipulation mod

The pattern across these is replay and constraint: they give you a reason to run familiar maps again under different rules. Always Pistol Start is the simplest example — it removes carried-over weapons so each level begins from the same baseline, which matters if you want consistent difficulty or fair run comparisons.

Utility tools

  • WadSmoosh — an IWAD merging utility. It combines official Doom WADs into a single merged IWAD, which is what makes a single continuous playthrough possible.
  • JP's Secret Finder — for UZDoom; finds items, secrets, monsters, and keys.
  • Full Run for WadSmoosh'd UZDoom — every official Doom level in one long playthrough, built on top of a smooshed IWAD.

WadSmoosh and Full Run work as a pair: merge first, then play the combined set. Secret Finder is the lookup tool for when you want to locate what's left on a map rather than hunt blind.

HUD and stat tools

  • JP's HUD mod — a readability-focused ZScript HUD mod.
  • Run Stat Tracker for UZDoom — tracks run times and many other stats.

These are for players who want information on screen or recorded across attempts; they don't alter gameplay.

Content release

Works of the Masters is a Deluxe Edition of the Master Levels for Doom II — a curated package of official Master Levels content rather than a rules mod.

How to choose

  • Want a new way to play existing maps → start with Phobos Minute or Green Demon Challenge.
  • Want consistent, comparable runs → Always Pistol Start plus Run Stat Tracker.
  • Want one continuous campaign → WadSmoosh, then Full Run.
  • Want to find what you missed → JP's Secret Finder.
  • Want a cleaner on-screen read → JP's HUD mod.

Because several items are explicitly labeled for UZDoom, confirm your source port matches before installing; the page does not state compatibility with other ports.
