So I’m pretty sure there’s a huge ARG hidden in Half-Life: Alyx that no one seems to have caught onto yet.

At the start of the game, if you turn the radio dial clockwise, you reach a station playing some very fuzzy music. However, if you pull the antenna out and very slowly turn the dial to the left end of the spectrum... you’ll eventually reach a ‘numbers station’. It seems to have some unique noises playing in it as well.

Additionally, when entering the North Star hotel, on the first floor in the bar there is a radio on the table in the middle of the bar.

You can’t interact with this radio, but it will briefly play a portion of a number station as well. I’m not sure if it’s the same recording or a different one.

This is really reminding me of the Portal 1 ARG with the radios that led into the Portal 2 announcement and release with the ARG players rebooting GlADoS

I have absolutely no skills with this, and can’t find a single post or video on the internet about this. I’m letting y’all know in case anyone knows how to trawl the files and find the sound file for the number station, or more than just the one if there’s any more
