The Jack Hack is a game of beating the odds in the depravity of late Victorian London. It has a focus on the Whitechapel area around the time of the infamous Jack the Ripper murders. The game could have been called Hack the Ripper. Maybe not.

This is the second edition. This edition contains all the rules needed to run the Jack Hack, and character creation. It differs slightly from the original base Black Hack RPG in the way attributes are generated. The level cap is five.
