What is the name of the file with Liberty prisons music?

Well, it's from this music:

Hope it helps

well... i thought it would be a nice easter egg (just like some others)

It is

There is another thread with this music, where a guy was going crazy with this music (and searching for it)

I also loved the ambient in prisons... as a cop.

hehe i lol'd so hard when i docked the first time with a prison. i was like just sitting there a couple of minutes listening to this "funny" song^^ nice easteregg, indeed

well ... knowing the movie you can just imagine how the prisoners try to dig tunnels

Nope, I don't.

Plastic forks/knifes won't make any tunnel or even a scratch on metal walls... not that tunnels in a box in middle of emptyness would be a good idea anyway.
