Chaos Zero Nightmare - Main Menu

Main-menu backgrounds, BGM, and startup titles for Slay the Spire 2 v0. 2. 1-beta

Replaces the Slay the Spire 2 main menu with Chaos Zero Nightmare backgrounds, music, and startup titles - and lets you use your own images as menu backgrounds. Gameplay and balance stay vanilla.

Version / Branch

  • []This file is v0. 2. 1-beta and is compatible with Slay the Spire 2 Beta v0. 111. 0.[/]

    []It does not work on the v0. 107. 1 official (Major) branch. Running it there can break game startup or menu presentation.[/]

    []There is currently no official-branch build. Use the Beta branch before installing it.[/]

    Quick Facts

    • []Menu backgrounds: the official CZN login CG, eight official illustration backgrounds, and nine official videos, including two promotional videos, played full-screen behind the menu.[/]

      []Menu BGM: fourteen official CZN tracks, selectable independently, with a Mod-only volume slider.[/]

      []Your own images: drop images into the Mod folder, name them in-game, and pair each one with a BGM.[/]

      []Startup title: a short CZN x STS2 title with a random Japanese title voice from your installed CZN character skins, either official promotional video, the original STS2 logo animation, or nothing at all.[/]

      []Character lobbies: installed CZN character skins automatically contribute their live lobby scene as an extra background.[/]

      []Standalone: no character skin is required and none is hard-depended on. Skins only add extra backgrounds and title voices.[/]

      []Multiplayer friendly: this is a menu-only Mod; other players are unaffected.[/]

      []Menu text in English, Traditional Chinese, Simplified Chinese, Japanese, and Korean.[/]

      []No gameplay, card, relic, power, damage, or balance changes.[/]

      v0. 2. 1-beta Update

      • []Adds a default-on CZN Logo switch to CznMainMenu's own right-side control panel.[/]

        []The switch only shows or hides CznMainMenu's lower-left title lockup on custom CZN or imported backgrounds.[/]

        Installation

        • []Open your Slay the Spire 2 game folder.[/]

          []Create a mods folder if it does not already exist.[/]

          []Extract CznMainMenu into that mods folder.[/]

          []Launch Slay the Spire 2 with mods enabled.[/]

          Slay the Spire 2

          └── CznMainMenu

          ├── CznMainMenu.dll

          ├── CznMainMenu.json

          └── CznMainMenu.pck

          Using Your Own Images

          • []Open the drawer on the right side of the main menu, then the Background tab.[/]

            []Press + Add custom background, then Open folder.[/]

            []Put PNG / JPG / WEBP / BMP files in the folder that opens.[/]

            []Back in the game, pick the file, type a name, choose its BGM, and press Save.[/]

            []Custom entries can be edited or removed later. Removing an entry never deletes your image file.[/]

            %APPDATA%\SlayTheSpire2\CznModConfig\CznMainMenu\backgrounds

            Images you import stay on your own PC. They are never packaged, uploaded, or redistributed by this Mod.

            Settings

            • []All options live in the drawer on the right side of the main menu. No separate ModConfig installation is required.[/]

              []Use CZN Logo to show or hide CznMainMenu's lower-left title lockup on custom backgrounds. This setting is enabled by default.[/]

              []Selections apply immediately and persist to

              user://CznModConfig/CznMainMenu/settings.cfg.[/]

              []Reset uses a two-press confirmation and restores every Mod setting.[/]

              []Escape or controller Cancel closes the drawer; controller focus connects the STS2 menu, the handle, and every drawer control.[/]

              Notes

              []The download is large because the official menu videos are included; expect roughly 260 MB of disk use.[/]

              []Video backgrounds decode continuously while the menu is open. If the menu feels heavy on a low-end PC, use the CZN login CG, one of your own images, or the STS2 background instead.[/]

              [*]Unreadable or removed custom images fall back to the CZN default login CG instead of leaving an em
