GTA NANDED
उगं नव्हं मय, नांदेड हाय नांदेड! — an open-world game of Nanded, Maharashtra, that runs in your browser at gta.nanded.fun.
Steal an auto-rickshaw outside Hazur Sahib Nanded station, weave through Shyam Nagar's coaching traffic, outrun Inspector Kadam's jeeps across the Godavari, and drive fares to real places across the city. The street map is the real one (OpenStreetMap); the 67,000 buildings, the traffic, the people, the sound and the music are all generated live in the browser.

Story: Godavari Gold (10 missions). Sunny Patil comes home from Pune, jobless, to find his father has borrowed two lakh from Kaka Savkar, a moneylender at ten per cent a month, and now owes six. To pay it he steals bikes for Bunty at Taroda Naka, chases down a matka collector for Shera, and runs sand at night for Jaggu Mama, who mines the Godavari: past the flying squad, out of the impound yard, and in a race for the river against Tiger. When Mama hides ganja under a tempo of onions from the Telangana road, Sunny drives it to Inspector Kadam instead. He stops Shera's protection racket, breaks into Savkar's office on Diwali night for the ledger that ties the loans to Mama's sand money, and has it out with Mama at the ghat. These are the kinds of crime Nanded’s police deal with; every character and event is fictional. Contacts appear on the radar and map with their initials: walk into a marker to start.
Around town.
- Rickshaw fares — in any auto press
N: pick up people waving at the kerb and drive them to one of 133 researched real places. Fast, clean rides tip; streaks pay more.
- Bhookh Express — on any bike or scooty press
N: collect from real restaurants, deliver while it's hot.
- Street races — Nanded Circle and Station to Airport, against rivals who play dirty.
- Landmark passport — photograph 17 landmarks (Hazur Sahib, the ghats, Nandgiri Fort, Kaleshwar, Vishnupuri Dam…) for stamps.
- Photos — 📷 (or
X) takes a photo anywhere, captioned with the place. Share hands it to WhatsApp, Instagram or anything else on the phone, with the game's link; Save keeps it.
- Roadside snacks — chai, vada pav, misal at stalls and handcarts heal you and give you a burst of energy.
- Anna's Rang Garage — drive in while wanted: new colour, repairs, stars cleared (₹250).
- Wanted level — crimes the police see (or a witness reports) earn stars. Jeeps path-find to you and ram; officers get out with lathis. Break line of sight and leave the flashing search area on the radar to lose them, or end up BUSTED at Vazirabad Police Station. Get hurt too badly and it's WASTED — you wake up at SGGS Civil Hospital.
- Radio — three stations composed live: Radio Godavari 92.7 (dhol-tasha), Lavani Express 98.3 (dholki and harmonium), Katta Lo-Fi 101.1. Every song is new.
- Neighbourhoods — 53 of them; each first visit pays ₹50. A full day passes in about 20 real minutes, and the weather can be clear, hazy or monsoon.
Progress saves automatically on your device. Graphics tune themselves to your device the first time you play and keep adjusting as you go (Settings → Graphics to pin Fast / Balanced / High / Ultra; Settings → Frame rate for 60 fps or a 30 fps battery saver; Settings → Performance readout to see what your device is doing). On a phone, add the game to your Home Screen (Settings → Home Screen) and it opens full screen, and an iPhone keeps your progress even after a week away.
How it's built
Everything is plain JavaScript modules on Three.js with Vite; there is no game engine, physics engine or texture file.
- World data —
scripts/build-world.mjs folds the OSM street graph (26k segments) into 17,861 road polylines between 13,373 junctions, keeping each road's one-way direction (1,368 are one-way, most of them the two carriageways of a divided road), plus rivers, the railway, the airport's runway, taxiways and aprons, the mapped petrol pumps, 1,185 mapped building footprints and 133 researched places, into public/data/world.json (460 KB gzipped). At load, roadnet.js lifts every bridge on dry land that crosses a street or the railway into a flyover: ramps of 8% from the ground (running on along straight approaches where the mapped bridge is short) up to a 6.4 m deck over what it crosses, on piers. Traffic, the player and the police drive up onto the deck or along the street beneath it, and collisions know which level they are on.
- City generation (
src/world/citygen.js) — zones by neighbourhood (old city, coaching hub, markets, residential, Vishnupuri campus, outskirts), lots along every street and infill in block interiors, trees, poles and wires, stalls, shrines and hoardings. Busy roads get a footpath that buildings keep behind; shop platforms and compound walls leave the kerb free. A divided road, mapped as two one-way carriageways only metres apart at half scale, is laid out as one: each carriageway keeps its kerb and footpath on the outside and meets the other at a kerbed median that carries the street lamps. Petrol pumps stand at the four mapped in OSM and along the highways (forecourt, canopy, dispensers, kiosk, price board; generic liveries), and a dozen sabzi markets line busy old-town streets with handcarts and mats of vegetables under umbrellas, sellers and shoppers. The railway is laid as broad-gauge track on ballast and sleepers, flush with the road at level crossings. Around Hazur Sahib the old town stays at two storeys. Deterministic: the same city on every device.
- Street architecture (
chunks.js) — buildings that front a street stand on a plinth, with slab edges at every floor, chajjas over the windows, corner pilasters, a projecting roof slab, balconies with MS railings or concrete balustrades, and a ground floor laid out bay by bay: a door with a step and canopy for homes, a raised platform (ota) under awnings for shops. Walls that face open ground get windows; party walls stay blank. This is an original illustration of the common Marathwada RCC street building, not a survey of any real facade.
- Rendering — a procedural texture atlas painted on canvas at load (
src/world/atlas.js: facades with grilles and chajjas, shopfronts, Marathi/English signboards, worn asphalt, kerbs) and one physically based shader for the whole city (citymat.js: glass that reflects the sky with a room behind every window, lit or dark at night; per-building weathering, damp plinths and rain streaks, and plaster fallen away to the brick, placed along each wall so it never repeats and heaviest on old lime-washed houses; puddles in the monsoon; a world-space detail texture so repeats disappear), so each 192 m chunk is a single draw call; chunks stream around you, built a few dozen buildings at a time between frames so that streaming never stalls a frame for a whole chunk. Chunks more than about 150 m away are built as a far version first: the same blocks in the same paint and windows, with their roofs, tanks and hoardings, but none of the balconies, chajjas, railings, awnings, signs, wires or small props, for a third of the triangles and fewer draw calls; the close-up replaces it as you come near. Trees are crowns of painted leaf cards that sway and cast dappled shadows (). Landmarks are hand-built (), with gilded domes: Hazur Sahib with its fluted dome, jharokhas, the Angitha Sahib and the tall Nishan Sahib; Hazur Sahib Nanded station turned to run along the line, with Platform 1, a foot overbridge over the yard, overhead-line masts and a train at the platform; the central bus stand's angled bays under a red shed; the airport's glass terminal, control tower and a turboprop on the apron beside runway 10/28 (); and Chhatrapati Shivaji Maharaj on a rearing horse at Shivaji Putla. Lal Pari buses wait at the bus stand's bays, autos at the station and cars at the pumps whenever you come near (). Sky, sun, moon, clouds and weather in , which also captures the sky into a small cube map that lights and reflects everything; on Balanced and up the sun casts shadows across streets and facades, and the shade gets the warm light that sunlit dust bounces back into it; the Godavari in . Vehicles are instanced by type, and the whole crowd is three instanced meshes on one skeleton: the processor poses each skeleton and writes its bones into a small float texture, and the graphics chip bends the body to them. Each frame sends only the instances in use (about 60 KB, where it used to send all the room there is for them, about 650 KB).
On an Intel Iris Xe laptop a typical street frame on High costs about 3 ms of CPU and 8 ms of GPU at 1576×863 with shadows, MSAA and bloom (~200 draw calls); Fast skips shadows, MSAA, bloom and wet reflections. The whole game is about 0.8 MB to download (brotli), plus 1.6 MB of cover art, music and fonts. Streaming builds each chunk in slices of under a millisecond within a per-frame budget of at most 4 ms. Measured in headless Chrome on the same laptop at 1280×720, the most streaming work any frame did on the test routes is about 5–6 ms (it was 15–27 ms when a chunk was built in one go), or about 11 ms with the CPU slowed 4× in DevTools (it was 35–77 ms). That emulation is not a phone measurement.

The city is an illustration on the real street map, not a survey: distances are compressed to half scale and buildings are generated. Their architecture is loosely inspired by typical Marathwada streets (Shyam Nagar's coaching blocks, Old Mondha's bazaar, Station Road); no facade, shop or landmark is a measured replica.
Analytics. gta.nanded.fun counts visits, game starts (new story, continue or free roam) and passed missions with Google Analytics 4, with advertising features and Google signals off. Every page address is reported as the bare domain, and no other host sends anything, so local builds and previews stay silent (public/analytics.js).
