BREAKMASS by Tront

BREAKMASS is a free voxel destruction sandbox in the browser. The city is the ammunition: grab a building with the God Hand, twist it, crush it, or throw it through the one next door, and watch real rigid-body collapses as the pieces come apart. Rockets, bomb rain and fracture archetypes give each structure its own way of failing, and the rubble stays where it lands.

It runs on Three.js for rendering and the Rapier physics engine for the collapses, all in a single HTML file with no install. Fly with Q and E, look around with the mouse, and use the contract HUD to score demolitions. It was written by Tront (Trent Sterling) with AI coding tools, tested with a headless browser harness, and it lives on tront.xyz next to the rest of the browser games.
