Drivable today: 1 km² · 940 buildings · 4,364 trees and shrubs

What you can do today

02TodayStart: station · 2’736’927 / 1’252’807

An early version (Closed Alpha 0.16.0), but already playable:

  1. Drive and drift

    Drifts with tyre smoke and long skid marks, real driving physics and an engine sound of its own for every car. Plus chase, bonnet and cockpit cameras, and with the G key (on a phone, tap “Kamera” until “Kino” comes up) the cinema camera: driving like in a film. You switch the car radio off with Q.

  2. Races with friends

    At a start flag you race with up to eight cars. On your own you drive a time trial against your own ghost car or drift for points in the drift zone. The map shows the start flags and the track, the line follows the roads, and online your best results go on the leaderboard with your game account.

  3. Räuber und Poli (cops and robbers)

    At the police post you open a round of “Räuber und Poli” online: one or two cops hunt the robbers, the robbers get a ten-second head start, and if a cop keeps contact with your car for three seconds, you’re caught. A round lasts three minutes. Three patrol cars stand in the post’s yard, you can drive them, and their front doors open.

  4. Get out and walk

    Leave the car as Maria, a hand on the door, and walk through Gossau, in first person too. On computers as well as on phones and tablets, there by touch.

  5. Day, night and rain

    The street lamps come on, shop windows glow, and the headlights throw their light on the wet road. In the rain the tyres throw up spray and leave wet tracks, and the trees turn with the real season.

  6. Online with friends

    The first online sessions with friends are running, by invitation and with your own account: you can sign in with a passkey too.

  7. Traffic in Gossau

    Other cars drive the streets, online and in single player: the same roundabouts, the same right-of-way, by day, night and rain, and at junctions they turn in smooth curves. In single player they honk when you’re in their way, pass you and stop with their hazard lights on after a crash. Plus the Säntis on the horizon, the minimap with a map and a GPS that guides you through Gossau.

  8. Computer, phone, tablet

    Keyboard and mouse, gamepad or touch. G-CITY adapts the graphics to your device and asks on first start whether it may send anonymous performance data. On a phone the picture is now sharper and calmer, with shadows, and you install it like an app.

  9. The real kilometre

    The station, the Andreaskirche and St. Gallerstrasse as models of their own, parked cars in the measured parking bays, plus made-up brands like the Spiessbürger kebab shop, which you can now also see from the inside on a computer with strong graphics, and the private bank Chlütter & Co. The loading screen shows 11 pictures from Gossau.

What’s coming

04NextTown of Gossau SG · BFS 3443

No dates, but a plan. Dashed lines are planned routes:

Maria at the wheel of the dark SUV at night, in the warm light of the cabin, looking ahead at the road.
Maria, the main character. A still from the trailer.

  1. Tuning garage

    A garage on St. Gallerstrasse where you tune your car: power in three stages, paint, tyre smoke and underglow. Much of it is built but still switched off.

  2. Your own characters

    More playable characters beside Maria, the main character since Closed Alpha 0.13.

  3. A living town

    Cars that honk and swerve online, plus pedestrians on the pavements and trains on a timetable.

  4. Police

    A wanted level in steps: the first two steps, with patrols that chase and arrest you, are built but still switched off. Roadblocks and a helicopter come later. “Räuber und Poli” at the post is already here.

  5. Missions

    A mission system and the first three jobs, including a heist as a team.

  6. Shops and a phone

    Shops you can walk into, money and a phone with contacts.

  7. More vehicles

    Motorbikes, bicycles, buses, trucks, a helicopter, fire engines and ambulances.

  8. All of Gossau

    The whole town, then a small airfield.

  9. Switzerland as one map

    After Gossau: St. Gallen, a compact Zürich with its lake and airport, Lake Constance and the Säntis with a small ski area. Every city 1:1 from official survey data, put together into one map.

  10. Open to everyone

    A lobby in the game, and later access for everyone, without an invitation.

How we build Gossau

05Gossau 1:11 km² · 2’736’750 / 1’253’000

Nothing is modelled by eye. Terrain, streets, buildings and trees come from the official data of swisstopo, the cadastral survey of the Canton of St. Gallen and the federal building register. Every deviation is measured; the numbers come from our validation reports.

  • 940buildings

    stand in the square kilometre around the station. 887 of them are swisstopo 3D models, the rest come from the cadastral survey and the lidar.

    Buildings report, 26 Sep 2026

  • 914/920

    cadastral buildings are in the game. The six missing ones are small sheds with no height measurement.

    Buildings report, 26 Sep 2026

  • 4,364trees and shrubs

    from the 2024 lidar flight and swissTLM3D, with their measured height and crown.

    Trees report, 26 Sep 2026

  • 98.7%

    of the buildings are linked to the federal building register: year of construction, storeys and use shape their facades.

    Buildings report, 26 Sep 2026

  • 2.4mm

    largest gap between the ground you see and the ground the driving physics runs on (away from the kerbs).

    Terrain report, 26 Sep 2026

  • 6.6cm

    is the median kerb height, measured at 25,205 points in the laser data, not guessed.

Frequently asked

07Questions

What does G-CITY cost?

Nothing. G-CITY is free and non-commercial: no ads, no shop.

When can I play?

G-CITY is an early version. Play is by invitation: we let new testers in continuously, as server capacity allows. Sign up and tick “I’d like to test now” – we’ll get in touch when it fits.

Do I need to install anything?

No, G-CITY runs in the browser. On a phone you put it on your home screen like an app.

Which devices does it run on?

On computers with keyboard and mouse, on phones and tablets by touch, and everywhere with a gamepad too. The graphics adapt to your device. G-CITY is an early version, and we have tested only a few phones so far. On some phones the game may close after loading. We are looking into it. If it happens to you, please write to hello@gcity.ch with the model and the iOS or Android version.

Is it really Gossau?

Yes, Gossau SG: this is where G-CITY starts. Terrain, streets, buildings and trees come from the official Swiss survey data – more in “How we build Gossau” above.

Is Zürich coming too?

Yes, later: after Gossau come St. Gallen, a compact Zürich with its lake and airport, Lake Constance and the Säntis, all 1:1 from official survey data. There is no date yet.

What happens to my address?

We only write to you about G-CITY: when it opens to everyone, when we’re looking for testers, and now and then with short news. Every email has an unsubscribe link. More in the privacy notice.
