About this mod Author’s original text

UndoEverywhere

A Monster Train 2 mod that lets you undo out-of-combat mistakes — shop purchases,

event choices, path picks — which the game otherwise offers no undo for.

The pause menu's Restart Battle button now also works on the map, where it

relabels itself Restart Ring. It rewinds the run to the moment the last

battle ended, or to the start of the run if you haven't fought one yet. Battles

you've already won stay won.

The mod snapshots your save at each of those boundaries (a.stagestart file

next to the real save) and restores it through the game's own load path, so gold,

relics, deck and map position all come back as the game itself would load them.

Install

Install SpecialCircumstances-UndoEverywhere with a mod manager (Gale, r2modman,

Mod Manager); dependencies come with it. Manual install: drop

UndoEverywhere.dll into BepInEx/plugins.

Known limitations

  • The button is available throughout the first ring, where it rewinds to the

run's start.

  • The ring confirmation dialog is English-only; every other language still sees

the vanilla battle wording.

Build

dotnet build

Patches live in UndoEverywhere/patches. Build,

environment and deploy details are in the meta-repo's CLAUDE.md.

Install & use Install: follow the bundled instructions

  1. Unzip the archive from playbuff and read the bundled readme / instructions first.
  2. Most mods rely on the game's mod loader — the usual route is a community mod manager (such as r2modman): pick this game, install, and it handles the loader and dependencies.
  3. For a manual install, put the mod files into the matching Mod / plugins folder inside the game directory.
  4. Launch the game to confirm it loaded; mods with listed dependencies need those installed as well.

Install locations vary a lot between mods — the bundled readme is the most reliable guide.

Dependencies

Install these first, or the mod will not work:
