Portal 2 escape music.
I'm sure you can gather what this mod does. You've surely seen a hundred other mods just like this one. It plays a song from a video game when the autopilot timer thing activates.
This uses and is built off of BGN's PizzaTowerEscapeMusic mod. Thanks to that guy for making a cool thing
The song in question: https://www.youtube.com/watch?v=p2vc7Zunsvk
I don't own this song or Portal 2 or Lethal Company or Pizza Tower or the original mod or pretty much anything for that matter
