This is Hong Kong, built from real map data: more than twenty thousand buildings on their real footprints, every street from Kennedy Town to North Point and from Tsim Sha Tsui to Mong Kok, and the mountains themselves, from real elevation data, with Victoria Peak standing over the harbour. Like the cities in the big open world games it is gently squeezed where real distance would only be dead time, so the harbour crossing and the drive over the hill to the south side are quick, while Central, Wan Chai and Kowloon are life-size. It is free, it runs in your browser with nothing to install, and everyone who opens it is in the same Hong Kong.
Two IFC, the International Commerce Centre, the Bank of China Tower, the HSBC Main Building, Jardine House, Central Plaza, the Convention and Exhibition Centre and Golden Bauhinia Square, the Observation Wheel, the Star Ferry piers, the Clock Tower, the Cultural Centre and the Space Museum at Tsim Sha Tsui, the Avenue of Stars, Temple Street, Mong Kok and Nathan Road, Lan Kwai Fong, the Mid-Levels Escalator, Man Mo Temple, Causeway Bay, Happy Valley, the Peak Tower, Lugard Road, Aberdeen Harbour and Ocean Park.
Multiplayer is built in. Everyone who opens insane.city/hongkong is in the same city, so send your friends the link and meet at the Star Ferry: you see each other walking, driving and flying in real time, and you can chat by pressing T. No accounts, no lobby, no sign-up.
Insane City also has New York City, all of Manhattan in 3D, and Meridian 2050, an invented coastal city with a Grand Prix circuit and fighter jets.

Insane City is free to play, and always will be to try. If you are enjoying it, you can chip in to back its development. We have not finalised how supporters will be thanked yet, so for now this is simply a way to support the game — early supporters will be remembered.

Hold Space to fast-forward · drag to look around
Drag orbit around the skyline. Scroll or pinch to zoom. Right-drag or two-finger drag to pan. Click any building to inspect it, or use the minimap to reframe.
↑ ↓ ← → orbit · + − zoom · Space pause · R reset · Esc close.
On a phone: everything is on screen. The pedals at the bottom right change with what you are in: GAS and BRAKE in the car, FWD and BACK with SPRINT on foot, throttle in the plane. The arrows on the left steer, turn or work the rudder. Drag anywhere on the world to look around, pinch to zoom in the overview, and tap the ⛶ button in the header for fullscreen. Hold two controls at once, for example gas and steering, and both register.

2050 gameplay: Space jumps on foot; E gets out of your car or re-enters it when nearby. Your parked car stays in the world. Physical portal fields now activate when entered, with E and a visible interaction button as alternatives. World controls reveals the simulation and graphics settings.
Walk explores the city in third person with an athletic character: WASD runs, drag looks freely, Shift sprints, and R recovers. Use Architecture Walks to visit landmark plazas. The main island now has nine times its original land area, plus an airport island.
Fly plane starts airborne over the bay. W/S adjust throttle, A/D control rudder, U/J pitch down/up, and H/K roll left/right. Numpad 8/5/4/6 also works. Buildings and water cause an arcade crash; R respawns. Drag to look around in either vehicle; C recenters.
Drive puts you behind the wheel in third person. Tap N for a burst of nitrous rather than holding it. Clipping something at a shallow angle now glances off and slides along it instead of stopping you dead. Two cars roll out of the garage, a mid-engined hypercar and a front-engined V12 grand tourer, in a fresh colour each time you take one; both are original designs inspired by the genre, not replicas. WASD drive, Space handbrake, Shift boost, R recover, Esc exit. Click the scene if keys are not responding. Driving uses simplified arcade physics.
Wind field reveals animated streamlines. Structure reveals conceptual exoskeletons. Flyover takes a slow cinematic orbit. Every view stays interactive.
Meridian Bay is an invented city. Dimensions, wind flow, traffic, and structural systems are illustrative-not measured data, CFD, or safety analysis. With a reduced-motion preference the city keeps running, but camera shake, speed streaks, field-of-view surges, most of the head bob and strobing fireworks are turned down.
Raven fighter: Space or Launch fires large unguided arcade missiles, with six rounds and automatic rearm. Other players in aircraft can be shot down - a direct hit destroys their Raven and they respawn with R. Everyone on foot, in a car or on a jetpack still passes harmlessly through each other; only aircraft can be hurt. Kills are tallied beside each name in the players panel. Gear-up flight is faster; G lowers the gear for the airport approach speed range. Space remains airbrake. Explosions are stylized game effects; the city stays intact.
Airport landing: press L to line up with runway 09. G toggles landing gear. Approach aligned and nearly level with a gentle descent and moderate speed; S reduces throttle, Space brakes. After touchdown, use A/D to taxi and W + J for takeoff. This is an arcade landing model, not pilot training.
Landscape journeys: Golden Dunes lies west of the city; Frostline Peaks lies north. Glasswater Lake feeds the upper stream, Cascade Falls, and Silver River. Use the atlas’s World view or the walking destination selector. Terrain and water routes are fictional, stylized landscapes.
Metro & Portals: Metro boards the elevated M1 loop. Exit at the next station or use Exit now to arrive on foot; drag looks around. Portals pauses only your player while choosing; trains and world activity keep running. Travel is instantaneous and arrivals are on foot. Approach an in-world portal and press E or walk through the field to open the same network.
The oversized Saturn and hovering UFOs are deliberate fantasy elements. Jeddah Tower is shown as a future-completed design study; the actual project is under construction and its published design exceeds 1,000 metres. It does not replace the completed-building top-ten ranking.
Persistent world, random player spawns: Walk, Drive and Fly choose safe varied starting places without regenerating the map. Metro boarding attaches to an existing train instead of restarting its timetable. Portal menus pause only the local player. Explicit World Pause remains a single-player control. The shared-state snapshot is groundwork for multiplayer, not a multiplayer server.
Content: Insane City contains stylised cartoon violence. Driving into pedestrians knocks them down and leaves blood on the road. It is a low-poly fiction with no gore detail, but this game is for players aged 18 and over. Turn Traffic off in World controls to remove pedestrians entirely.
Jetpack: flies on the same control map as the Raven. W/S set throttle, U/J pitch the nose down/up, H/K roll (banking turns you), A/D yaw. Thrust is vectored along the nose, so pitch down and you dive. Space still gives direct lift and Shift direct descent for takeoff and landing; Q+E holds a hover and brakes everything. On the ground F takes the pack off; in the air F throws you clear and opens the parachute if you have the height for it. There is no fall damage anywhere in this world: land without a canopy and you simply bounce. The jetpack attaches at your current on-foot location; from other modes it uses a safe player spawn. This is an original arcade implementation inspired by San Andreas controls.
