# How to Install Reunion & ReHLDS in CS 1.6

> Modernize your Counter-Strike 1.6 server infrastructure. Learn how to deploy ReHLDS for improved performance and Reunion for cross-client compatibility.

## Modernizing the Legacy Engine

While the original Valve GoldSource binaries remain the official standard, many professional community servers transition to **ReHLDS** (Reverse-engineered Half-Life Dedicated Server) and **Reunion** to achieve superior stability and security. ReHLDS serves as a high-performance replacement for the stock engine core, fixing decades of unpatched vulnerabilities and optimizing CPU utilization. Reunion (the successor to the legacy Dproto) enables cross-client compatibility, allowing your server to accommodate a wider variety of participants. This guide walk you through the technical modernization of your classic CS 1.6 instance.

## Technical Advantages of ReHLDS

Replacing your stock engine core with ReHLDS provides several critical infrastructure benefits.

* **Security Hardening:** Natively patches multiple "Exploit" packets and buffer overflow vulnerabilities that can be utilized to crash standard Valve servers.
* **Performance Optimization:** Implements more efficient mathematical logic for entity movement and networking, leading to a more consistent 1000 FPS experience.
* **Enhanced Logging:** Provides more granular diagnostic data within the console, facilitating easier technical troubleshooting.

## Technical Implementation Workflow

Reunion operates as a high-priority Metamod plugin and must be initialized early in the boot sequence.

<Steps>
  <Step title="Deploy Binary Assets">
    Upload the Reunion modification folder into your `/cstrike/addons/reunion/` directory via the File Manager or SFTP.
  </Step>

  <Step title="Register the Plugin">
    Open your Metamod configuration file situated at `/cstrike/addons/metamod/plugins.ini`. Add the following line at the **top** of the list:

    * *Linux:* `linux addons/reunion/reunion_mm_i386.so`
  </Step>

  <Step title="Configure Identity Logic">
    Open the `reunion.cfg` file located in your root directory. This file dictates how the engine assigns SteamIDs to different client types. We recommend using the "Unique ID" logic to ensure persistent ranking and ban records.
  </Step>
</Steps>
