From publisher blurb:
An adventure for Chav: The Knifing which also draws on Wizkid: the Cheapening, Bloodsucker: the Angst and the as-yet-unpublished Dogboy. Viper in the Nest takes you into the supernatural gang culture of 'Chavs', self-appointed hunters, or at least beater-uppers, of the other supernatural denizens of the Shadow World.
Vipers in the Nest is a relatively straight interpretation of the Shadow World with lots of violence and taking the mick out of the way the games it is parodying tended to be played.
An Xpress adventure for 4+ players.
