Install the Silkless Co-Op mod for Hollow Knight Silksong on PC with our step-by-step guide. Play with friends, troubleshoot issues, and explore Pharloom together.
The Silkless Co-Op mod lets you see friends in your Silksong playthrough (visual co-op only, no actual interaction). Download BepInEx 4 and SilklessCoop.zip from Nexusmods, extract to Silksong’s root folder, press F5 in-game to enable multiplayer. Steam integration allows easy friend joining via right-clicking Steam names.
While Hollow Knight: Silksong was designed as a solitary journey through the mysterious kingdom of Pharloom, the dedicated modding community has found ways to share this challenging adventure with friends. The Silkless Co-Op mod transforms the lonely exploration into a shared experience – even if it’s not true cooperative gameplay.
Having tested this mod extensively, I can tell you it creates genuinely memorable moments. While you can’t directly help each other fight bosses or solve puzzles, watching a friend struggle through the same challenging sections you’ve conquered (or vice versa) adds an entirely new dimension to the Silksong experience.
Understanding Silkless Co-Op: What It Actually Does
Visual Co-Op Experience
The Silkless Co-Op mod creates a “ghost multiplayer” experience where you can:
- See other players moving through the same areas
- Share exploration discoveries in real-time
- Experience story moments simultaneously
- Laugh together at shared deaths and victories
Important Limitations
What you CAN’T do:
- Directly interact with other players
- Help with boss fights (Elden Ring-style cooperation)
- Share items or resources
- Revive fallen teammates
What you CAN do:
- Explore areas together visually
- Coordinate movement and exploration
- Share the emotional journey of discovery
- Create shared memories of challenging encounters
This creates a unique “parallel play” experience that maintains Silksong’s intended difficulty while adding social elements.
Complete Installation Guide
Pre-Installation Requirements
- Platform: PC only (Steam recommended)
- Game: Hollow Knight: Silksong installed
- Access: Nexusmods account (free registration)
- Technical: Basic file extraction knowledge
Step 1: Download Required Files
Primary Downloads from Nexusmods:
- BepInEx 4 – Core modding framework
- SilklessCoop.zip – Main multiplayer mod files
Important: Both files are essential – BepInEx provides the foundation that allows SilklessCoop to function properly within Silksong’s architecture.
Step 2: Locate Silksong Installation Directory
For Steam Users (Automatic Path):
%USERPROFILE%/AppData/LocalLow/Team Cherry/Hollow Knight Silksong/Manual Steam Location Method:
- Open Steam Library
- Right-click Hollow Knight: Silksong
- Select “Properties”
- Navigate to “Local Files” tab
- Click “Browse Local Files”
Alternative Location Methods:
- Check your Steam installation directory (usually C:\Program Files (x86)\Steam\steamapps\common)

Step 3: File Extraction Process
Extraction Instructions:
- Extract BepInEx 4 directly into Silksong’s root game folder
- Extract SilklessCoop.zip into the same root directory
- Verify file placement – files should integrate with existing game structure
- Check permissions – ensure extracted files aren’t read-only
Critical placement note: Both archives should extract directly into the main Silksong folder, not into subfolders. The mod files need to integrate with the existing game directory structure.
