This guide will walk you through on how to launch custom Half-Life: Alyx levels that don’t use the Steam Workshop.

Step One: Enabling the developer console.

To start, we’ll enable the developer console. This lets you type in various commands that will allow you to enter your maps.

First, right click Half-Life: Alyx in your steam library, and select “properties” from the drop-down menu that appears.

Next, select “Set Launch Options” on the properties menu that is created.

Finally, type “-console -vconsole” into the launch options, then hit “OK.”

Step Two: Installing your level

Now we are going to install the level you’ve downloaded into the game.

Open the properties of Half-Life: Alyx again and go to Local Files, then select “Browse Local Files.”

Now Navigate to \SteamLibrary\steamapps\common\Half-Life Alyx\game\hlvr and open a new file explorer window where you have your downloaded map file.

Drag the map file into the folder called “maps.”
