The book itself contains lots of maps and descriptions. The city is fairly well developed, but not so well that you can t add a lot of your own surprises. There are also many, many NPCs in this book. It s an island prison after the mold of Alcatraz. Only this prison can hold guys who can level buildings with a punch.
Much detail is provided for the prison, it s staff and the inmates.
This book is also full of stuff. Gearheads will love this book. They managed to make over 90 Villains for this book as well. Everything from teams of terrorists, to singular lunatics, to fallen heroes fill Gramercy s cells. And the staff is very well developed.
