Public Nuisance
Public Nuisance is an open-world chaos sandbox set in a town called Maplewood: drive, walk, jump in and out of vehicles, grab coins, rack up chaos, and work through a set of mini-games scattered across the map whenever you get bored of just causing trouble.
It’s the closest thing on this site to a full open-world game, complete with its own physics, its own camera controls, and enough buttons mapped that you’ll want to glance at the control list before you start.
There’s no real objective beyond the score counter. Sometimes that’s exactly the point.
