# How to Install Winter Mods (Frosty) in ATS

> Install the Frosty Winter mod on your ATS server to add realistic snow physics, icy road handling, and stunning winter visuals for your convoy.

## Winter in the Wasteland

The Frosty Winter mod, developed by Grimes, dramatically transforms the landscape of American Truck Simulator (ATS) into a freezing winter environment. More than just a visual overhaul, it introduces sophisticated snow physics that fundamentally alter vehicle handling, providing a unique challenge for even the most experienced drivers.

## Installation & Deployment

Because the Frosty Winter mod is distributed as an external asset rather than through the Steam Workshop, it requires a manual installation process for both the server and every participating driver.

<Steps>
  <Step title="Acquire the Mod Files">
    Download the latest `.scs` files from the official [Grimes Mods](https://grimesmods.com/) website. Ensure you select the version that corresponds precisely with your active ATS version.
  </Step>

  <Step title="Upload to Server Directory">
    using the [Game Panel](https://panel.freakhosting.com) File Manager or an SFTP client, upload the `.scs` assets into the `/mod/` directory on your server.
  </Step>

  <Step title="Update the Server Manifest">
    Register the mod filenames within your server's package manifest (typically `server_packages.sii`) to ensure the server recognizes and enforces the mod requirement.
  </Step>

  <Step title="Synchronize with Drivers">
    Distribute the download links to all members of your convoy. Every player must have the identical file version in their local `mod` folder to prevent connection rejection.
  </Step>
</Steps>

## Impact on Driving Mechanics

The Frosty Winter mod is a gameplay-altering modification that requires a change in driving strategy.

<Tabs>
  <Tab title="Friction & Braking">
    Road surfaces lose significant traction. You will notice significantly extended braking distances and a high probability of jackknifing or sliding off the road when attempting high-speed maneuvers or sharp cornering.
  </Tab>

  <Tab title="Traction Challenges">
    Steep gradients become formidable obstacles. We recommend avoiding "Heavy Cargo" or "Special Transport" deliveries while this mod is active, as the lack of traction can render specific mountainous routes virtually impassable for heavily laden trucks.
  </Tab>
</Tabs>

<Warning>
  ### Critical Synchronization

  If a driver attempts to join without the mod active while the server has it enabled, they will experience severe physics "desync." Their truck will operate with standard road friction while others are sliding, leading to visual errors and collisions. Always ensure the entire convoy is using the exact same Frosty Winter files.
</Warning>

## Technical Optimization

<AccordionGroup>
  <Accordion title="Visual Performance">
    Winter mods introduce high-resolution snow textures and particles. If your drivers report FPS drops, encourage them to disable the "High Quality Snow" optional addon if they are using one.
  </Accordion>

  <Accordion title="Conflict Resolution">
    Ensure that no other weather or lighting mods are active simultaneously, as these frequently conflict with the specialized shaders used by the Frosty Winter mod.
