Mined Prison Secret Service description

Mined Prison: Secret Service (Chapter 3)
Mined Prison is a popular adventure map series where in each map you are in some way trapped in a prison and need to find a way out. In the previous chapter (also known as Test Subject) you managed to escape the evil hands of the Chief Warden and Dr. Hanks. Even if you are still stuck in a muddy cave under the prison it appears when you progress through the map that the future ahead looks a little bit brighter.
