Requires Custom OST mod by Nate https://modworkshop.net/mod/27359 All assault phases use different parts of Bad Apple. There is an alternative assault track that includes the most intense moment of the song (but also has a forced transition to the beggining). Plays with a 20% chance by default. The stealth track is a very short loop (only 7 seconds) so I strongly recommend against using this song during stealth.
