You can brawl special NPCs (conveniently named Brawlers, with a special icon to denote such) without death or unconsciousness. There is also a feature to arrest individuals (and execute arrested characters) that is subject to a fairly precise set of conditions that you can view on the rules pages. Actual combat against creatures is intended in the immediate future.
