From the introduction: An industrial revolution transformed Hell into a ruthless corporation. Trains ship souls to various places of torment and suffering. Hell’s minions put on uniforms and exchanged pitchforks for stun batons. Adventurers who are sentenced to Hell along with other damned souls travel by train and visit locations each embodying one of the 7 deadly sins. Players face challenges which tempt them to commit sins punishable by loss of body parts. Only if they resist temptation, atone for their dark past and embrace divine virtues, they earn their salvation.
