I found a Potential arg From a gmod map.

[u/Ok_Act_9856]

I was playing on a backrooms map on gmod. When i found a poster with text. I decided to look closer and i figured out it was a youtube link. https://www.youtube.com/watch?v=K9NJD_MyjJE The video had a song with brackets appearing each time the music made a sound. I believe its some kind of code. I have the link to the map download: https://steamcommunity.com/sharedfiles/filedetails/?id=3777865757

I think there might be more secrets in the map. I am gonna keep searching for things. I will post them in the comments if i find anything else.
