2.1 WH Launcher method

The WH Launcher was made to simplify multiplayer installation and help keep your game updated. Plus it can show current players and sessions. That's pretty much it. I made it as a person who hates launchers, so, no invasive stuff like autorun on system start up and sitting in a tray.

1. Download and install WH Launcher

Navigate to https://warehouse.games/launcher or just click here

2. Launch the WH Launcher

On first start-up (or later in settings) you can link the launcher to your website profile, which will download all the necessary files automatically.

In most cases this will be done automatically, if automated search fails - you can manually select the game folder on your PC.

4. Click “Update” button

This will download client files and add your multiplayer key.

5. Click “Play”

Or launch the game by hand. It's up to you.

This is the end of the guide for you, enjoy your game. You don't need to do any additional steps below.
