If you try to use commentary mode via the MMod version of Half-Life 2 Update, you will realise that it does not work. This guide outlines the steps to fix it.

This guide presumes you have an up to date install of Half-Life 2: MMod.

The first step is to copy the map commentary files from your Half-Life 2 Update installation into the HL2MMod_HL2U sourcemod.

Locate the files for HL2 Update. You can use do this easily via the cog menu in steam. Go to Manage > Browse local files


Copy all *_commentary.txt files found in Half-Life 2 Update\hl2\maps to the maps folder in the mmod sourcemod. Make sure to copy them all!
(Example: "Half-Life 2 Update\hl2\maps\d1_canals_01_commentary.txt" is copied to "Steam\steamapps\sourcemods\HL2MMod_HL2U\maps\")


This will fix commentary not working on any map. Follow the steps below to correctly enable commentary mode on a New Game.

If you start a new game with commentary enabled via the main menu, it fails to work. Checking the commentary cvar will show its been changed to 0 (disabling it). Setting the commentary cvar to 1 before will also not work as starting a new game will reset this cvar automatically to 0.

To correctly enable it, you need to enable the developer console. This can be done in Options > Keyboard > Advanced > Enable Developer Console. Pressing ` by default opens the dev console (you may have to rebind the 'Toggle developer console' entry for some keyboard langs)

Open the console just after starting a new game and run:

Then to reload the first map and keep commentary on, run:

This bypasses the automatic cvar changes applied when using the "New Game" option and restarts the first map.

You should now hear the introduction commentary! Commentary will continue to work for the whole playthrough 😄
