The country

Leave room
for a town.

Release land, connect roads and commission public facilities. Companies choose where to build. Households need homes, work and services.

Deliveries and commutes use the same roads. A busy junction can hold up more than the morning traffic.

Infrastructure

Across the district.

Connect homes and businesses to roads, transport and utilities. Delayed deliveries and interrupted services affect the people who depend on them.

Detailed rail structures and dock operations are visual concepts.

Government Mode

Keep the
services running.

Set taxes and public spending, expand infrastructure and inspect the businesses and households that depend on it.

Walk through an existing district in Enter City, then return to the country overview.

A separate narrative game

The Missing
Administration

You arrive for a handover. The government district is empty. Inside, the records do not explain where everyone went.

The separate Story Mode preview covers the prologue and Chapter 1. It is in development and is not yet available from the public launcher.

Development preview

Try it yourself.

The browser demo introduces Government Mode. The Windows launcher downloads the full game afterward.

This is not a stable final release. Keep backups of saves you want to retain.

Construction and transport

Three closer looks.

The simulation already includes construction, rail and freight. Some of the close-range detail shown here is planned rather than playable.

Unfinished building and tower crane beside the street — A worksite beside an occupied district.

Concept

Construction at street level

Contractors build the homes and facilities a growing settlement needs. Keep projects connected to roads and supplies.

More detailed scaffolding, cranes and worksite activity are planned.

Regional train crossing a railway bridge — Rail crosses above the street.

Concept

A train overhead

Rail provides connections beyond the local road network. Stations and their access roads need space as districts expand.

These elevated structures show the direction planned for closer views.

Truck and forklift at a raised warehouse dock — A delivery at the warehouse.

Concept

At the loading dock

Businesses depend on deliveries. A shortage upstream or a blocked road can leave another company waiting for supplies.

Close-range forklift and dock handling are planned visual details.

From the playable previews

Before installing

Useful to know.

Windows download warnings

A new unsigned installer may show “Windows protected your PC”. Check that you downloaded the official release and that its SHA-256 matches before considering “More info” and “Run anyway”. A matching hash is not a digital signature.

Do not disable Defender or SmartScreen. Do not bypass a threat detection. If Windows reports a threat rather than a reputation warning, stop and investigate.

Saves and demo import

Export the browser save and import it in the Windows game. No automatic cross-device synchronization is provided. Keep the exported file as a backup. Do not clear browser storage before exporting.

Where are my Windows saves?

The Unity country simulation keeps its saves in %USERPROFILE%\AppData\LocalLow\Signal City Lab\Signal City\SignalCity\Saves. A display-name change does not move this folder. The separate Unreal Story Mode has its own save data.

Preview limitations

The published game is a development preview, not a stable final release. Mobile gameplay is not certified. The separate Story Mode build is not yet published.

Use Display settings to choose reduced motion or still images. The demo and downloads remain available while a view loads.

Controls and accessibility

Scroll to move through the city, stop to pause, or scroll up to return. Section links and Page Up or Page Down move to the selected view. Home and End select the first and last views. Escape closes dialogs. Display settings includes still images and reduced motion.
