Characters in the game have two Attributes with numeric scores varying during play; Fight and Pain. In most respects, these two Attributes are antagonistic qualities.
One intriguing aspect of the game involves character's health and disease immunity: the characters are survivors of a plague, but they do not actually know whether they are immune... or just lucky. This adds a substantive amount of uncertainty and nuance to play.
The game is accessible and well-organized with very helpful play summaries presented in an appendix.
