This indie RPG is based on The Black Hack by David Black and its vampire derivative The Blood Hack by Matthew Skails.
The system is very simple: you test 6 Stats (the classic STR DEX CON INT WIS CHA) for all actions and sometimes roll Usage Dice (Soul, Grave and Mortal Coil) which degrade every time they come up 1 or 2.
This introductory scenario illustrates the distinctive features of the game and allows for a mixture of detective work, combat and emotional expression. Mature themes are alluded to but not explicit.
