Bounties
Put a price on a head — and let the city do the rest.
Can't reach someone yourself? Pay the city to. A bounty is a public purse on a player's head, and it comes in two flavors: a beat bounty, paid to whoever hospitalizes the target, and a kill bounty, paid to whoever ends them. The board is public — being listed on it changes how a player sleeps.
Placing one
Living with a price on your head
Bounties stack — several enemies can fund the same head, and a fat combined purse turns acquaintances into hunters. Your options: live carefully (the safe house exists for a reason), wait it out, or buy the contract off: the target can pay 3× a bounty's value to have it removed. Painful arithmetic, by design — it should always hurt more to erase a contract than to place one.
Placers can cancel their own bounty while it's unclaimed, but it's not a clean reversal: you get 90% of the principal back — the house keeps its 10% cut — and any anonymity fee you paid stays burned.
