Arkham City: a controversial supermax prison for the patients and inmates of the original Arkham Asylum, and Blackgate prison. Why is there controversy?

This project is led by the enigmatic Professor Hugo Strange. His goal: to divide Gotham City into two. The law-abiding citizens, and the criminals.

To the citizens of Gotham City, this Professor Strange was previously unheard of. Who, exactly, is he? Where has he come from? And just how was he able to convince Mayor Quincy of Gotham City into accepting this immense project?

Professor Strange was not alone, however. Accompanying his project was TYGER; an elite special forces unit, trained especially for the Arkham City project. Their purpose are to serve as the prison's correctional officers and guards, enforcing Professor Strange's regulations.

There are no definite requirements for a Gothamite to be incarcerated in Arkham City. Rumour is, that petty thugs, drug-dealers and mob bosses are not the only ones eligible for a prison sentence. If the Professor simply doesn't like you, you are qualified enough.

Prisoners are unceremoniously thrown into this walled-off region of Gotham, and are left to fend for themselves. Food crates are regularly deposited in certain districts and at specific times throughout each day, but it's up to the inmates themselves as to how it is distributed. Ordinary, everyday commodities have become treasures, and many are prepared to do what it takes to secure such valuables.
Many gangs roam the streets, and viciously guard their turf from one another. There are only a handful of regulations to comply with, and if not adhered to, the consequences are... deadly.

One thing is for certain, in this squalid sector.
