From cover:
Some call it the ultimate game, the surpeme test of cunning and strength. Others find it a barbaric blood sport, nothing more than barely contained mayhem that appeals to the most primitive blood lust lurking in the human psyche. For the shadowrunner, the world of Urban Brawl holds a Byzantine maze of betrayal, buried secrets, and sudden violence. So how about it, are you ready to rock and roll with the big boys?
Notes:
The back of the book includes the rules for urban brawl, also published in Shadowbeat, and DMZ stats are included for the characters in the urban brawl game the PCs get involved in, for those wanting to fight it out as a tactical skirmish. Rules of the adventure are compatible with both 1st and 2nd edition Shadowrun.
