Extracting Assets and Text - Alchyr/ModTemplate-StS2 GitHub Wiki

Slay the Spire 2 uses the Godot game engine, so if you're looking for base game assets and text, you will need to use GDRE Tools.

• Download GDRE Tools from Github (on the releases page; the latest release should be fine; expand the Assets section and download the one that matches your operation system)
• Extract GDRE Tools to a folder and run the .exe
• From the RE Tools menu, select Recover Project
• Open SlayTheSpire2.pck from the StS 2 install directory
• Wait for it to process the project

You can now browse through all the games assets. Text can be found under the localization folder. Other assets (images, scenes, sound, etc.) are distributed throughout various folders; the names are mostly sensible. The game's code is here too, under src/Core, though looking at it in a decompiler will be more convenient; see Decompiling.

If you want to reference assets more easily in the future, consider extracting the pck's contents to a folder of your own.
