Build a realistic open-world driving game where

APEX CITY is a fully offline open-world driving game. Drive the original AUREL GT8 performance sedan through a procedurally-generated city — day, sunset and night skies, rain with slippery reflective roads, a ring expressway, tunnel, bridge, gas stations, a drift arena and a parking lot — with six modes (Free Drive, Race, Time Trial, Drift, Parking, Traffic), AI traffic, and a full garage with paint, wheels and performance upgrades. No login, no ads, no internet required: it installs as a PWA and plays entirely from local storage.
