{% step %}

#### Preparation

* Download the R6S loader from the official [Crusader loader page](https://uniqueloader.com/r6s/).
* Extract it with WinRAR or 7-Zip into its own folder, ideally `C:\Crusader`. Use English letters only in the folder name.
* Set Rainbow Six Siege to Borderless or Windowed mode.
  {% endstep %}

{% step %}

#### First start

* Right click the loader and select Run as administrator.
* Paste your key into the Serial Key field and click Sign In.
* When the R6S icon appears, click Start Injection Process.
* When the loader says "Please open your game", start Rainbow Six Siege.
* Wait for the main menu, then press INSERT to open the menu.
  {% endstep %}
  {% endstepper %}

{% hint style="danger" %}
Disable your anti-virus (including Windows Defender real-time protection) before running the loader, otherwise it can block or delete files.
{% endhint %}

### **Troubleshooting: Common Issues and Fixes**

* The game crashes on start: make sure you are in Borderless, not Fullscreen.
* Using a spoofer? Always start the Crusader loader before the spoofer.
* Connection error in the loader: try a VPN such as Cloudflare WARP.
* ESP not working in Arcade mode: turn off Team Check in the menu.
* After a Siege update the cheat may need a quick update first. Open a ticket if it stops working.
