README

Mutators Addon

Unofficial extension for Xepos Mutators Adds extra mutator events to the Mutators.

Mutators

Name Effect
Watchdog Out! Elsa transforms on sight instead of waiting for pets; at least one Elsa spawns per run; leaves the level after raging. Config: Transform cooldown (default 50s).
MAP-side Down The Tab minimap screen is flipped 180°.
Silent Stalkers Enemy sounds are muted on your own client. Encounter/ambience sounds still play. Optional extra compatibility with Wesley's Enemies if installed.

Requires

This is an unofficial add-on. It does not include or redistribute Mutators source code; it only registers new mutators through the public API Mutators provides for third-party developers.

Credits

  • Xepos / Mutators — the mutator framework and public registration API this addon depends on. Huge thanks for making an extensible system; without it this addon wouldn't exist.
  • Watchdog Out! — the "transform on sight" idea is inspired by the built-in Duck This mutator; the implementation is original, Elsa-specific logic written for this addon.
  • GastrodonGroup — packaging and maintenance.

Disclaimer

The maintainer is not an experienced C# developer. Most of this codebase was written with AI assistance. It has been tested in small private lobbies, but please use at your own risk and report issues if you find any.

Installation

Use a mod manager (r2modman / Gale / Thunderstore Mod Manager) and install alongside Xepos Mutators. All players in a lobby should have the same mod set installed.
