Translated from the manual:
A prison. It's where the shit jerks who did too much are put.
A place where the rats who were either stupid or clumsy are kept separated from society until they cool down.
No one, no matter how crazy, wants to go there.
But there was one complete idiot who ended up in the special prison for violent maniacs.
...and that's you.
It's defended by a system that Alcatraz or Bastilles don't come near. A huge hell, finely constructed and full of patrols.
If you can get out of there, the next thing and you'll be able to break of out Hell itself.
Even so, this is your line:
"So what. I have to do it."
You have to, to save the guy on death roll, who was innocently judged.
Use your skill, your genius and your brains to the fullest.
What awaits you is unimportant. Your must save the man, get him out of there, think tactically, and use whatever tools you can get ahold of.
Got it? Good. Let's get going.
