If you were looking for an excuse to replay the excellent Half-Life: Alyx, now you have one. Valve has added more than three hours of developer audio commentary to the VR title, detailing nearly every aspect of its creation. To begin listening to the audio tracks, you’ll need to start a new game and select the “Developer Commentary” option before diving back into the world of City 17.
As you play your way through the game, you’ll encounter floating headphone icons strewn across the environment. To listen to a particular commentary track, all you need to do is pick up the cans and place them on Alyx’s head. In all, you’ll encounter 147 audio clips as you play through the game. Each one is in English, but you can follow along with subtitles in 10 other languages, including Chinese, French, German, Korean, Japanese and Russian.
