Made for clear, practical setup.Install Shadow Protocol in the game’s UE4SS Mods folder, start Lockdown Protocol normally, then use the companion to check the local connection and access supported tools.

Honest limits.
Shadow Protocol is a community-made project for private sessions and experimentation. It is not affiliated with or endorsed by the developers of Lockdown Protocol.
- Requires UE4SS installed for the game
- Separate Windows companion window; not an overlay
- Some actions are experimental or depend on a working in-game receiver
- Use only where you have permission and follow the game’s rules
A green connection check confirms that the local bridge replied. It does not guarantee that every game action will succeed.
Getting started
Three steps to launch.
Setup is local on your PC. Keep the game closed while installing or updating the Shadow Protocol files.
Install UE4SS
Set up a compatible UE4SS build for Lockdown Protocol first. Shadow Protocol works with the UE4SS Mods folder used by your game.
Install Shadow Protocol
Run the Shadow Protocol companion and use Setup / repair to select or detect the active Mods folder. Close the game before updating files.
Start the game
Launch Lockdown Protocol normally. Open the companion, check the connection, then try supported actions in a private session.
Quick answers
Before you dive in.
Short answers to the most common questions about this Lockdown Protocol mod companion.
Is Shadow Protocol an in-game overlay?
No. It is a separate Windows companion window. UE4SS runs the in-game mod component.
Do I need UE4SS?
Yes. Install a compatible UE4SS setup for Lockdown Protocol. Shadow Protocol’s setup helper installs its managed files into the selected UE4SS Mods folder; it does not replace UE4SS.
Do all tools work in every session?
No. Some actions depend on game state, the receiver, or the host. Player teleports, weapon changes, and other game actions are experimental and can be reversed by the game.
Where can I get updates or help?
Join the community Discord for project updates and setup help. The companion includes diagnostics for checking the selected folder and local bridge.
Is it listed on Nexus Mods?
This page does not claim a Nexus Mods listing. Check the community links for the current official project download and release notes.
Is this an official Lockdown Protocol product?
No. Shadow Protocol is an independent community project and is not affiliated with the game’s developers.
