Half-Life: Alyx is a hugely ambitious virtual reality title that Polygon called “the best that VR has to offer.” But what if you could find out more about Alyx and how the game was created? If you’re at all curious, the game’s new, free update looks to be a treat. There are three hours of developer commentary, which are subtitled in over 10 languages.
This is similar to the Half-Life 2 and Portal developer commentary modes, but in Alyx, the player can trigger the audio by taking an in-game headset and putting it on their head.
Valve published a trailer for the commentary on Thursday, which includes some intriguing stuff. It starts with very simple explanations for core gameplay elements or enemy pathing, then advances into more complicated topics like creating a bottle of water that the player can manipulate in virtual reality. We also get a taste of some less science-y topics, like the art of creating cute headcrabs and how to best convey an exploding abdomen.
The commentary is available in-game to all players who own Half-Life: Alyx.
