Press:
⏎ Enter
📂 If the Folder Does Not Exist
Create a new folder named:
📁 Mods
The full path usually looks like this:
📁 C:\Users\YourName\AppData\Roaming\Captain of Industry\Mods
⚠️ Important Warning
This is NOT the Steam game installation folder.
❌ Wrong location:
📁 Steam\steamapps\common\Captain of Industry

📁 %APPDATA%\Captain of Industry\Mods
Captain of Industry loads mods from the AppData folder.
🧰 3. Extract the Mod

✅ Quick Checklist
Before asking for help, check this list:
✅ The mod is extracted
✅ The mod is not still zipped

✅ The .dll is not buried too deep
✅ Mod support is enabled in-game

🧯 Troubleshooting
❓ The Mod Does Not Appear
First, check your folder structure.
The game usually expects:
📁 Mods\ModName\ModName.dll
Also make sure:
🔄 You restarted the game after enabling mods.
🔍 Very Important Extra Tip
Sometimes the mod actually loaded correctly, but the changes are difficult to notice at first. 👀
Many mods add things like:
🆕 New buttons
📚 New research
⚙️ Hidden settings
🏭 New buildings
📋 Extra menus
🔧 Small UI buttons
🧩 Features inside existing systems
Some modders show beautiful screenshots of what the mod does, but do not always explain:
❓ Where to find the new feature
❓ How to activate it
❓ Which menu changed
This can make it look like the mod failed to load, even when it is working perfectly.
💡 What You Should Do? 🤔
Before assuming the mod is broken:
✅ Carefully read the mod description
✅ Look at screenshots closely
✅ Search for new UI buttons or research
✅ Check build menus and research trees
✅ Read comments/discussions if available
Sometimes the mod feature is simply “hidden” somewhere unexpected. 🔎
This tip alone can save a LOT of confusion for new players — and save modders a lot of support time too. ❤️
If you are unclear about something, don't afraid to ask the modders directly! They are very nice people~
