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.[/]

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
