City Masterplan - PC (Steam)

Build at a True 1:1 Scale — No Grid Limits

City Masterplan is a city-building simulation where true-scale construction meets flexible, grid-free planning.

Design your city without constraints — draw roads freely, build complex highways, and develop diverse districts at a true 1:1 scale.

From terrain sculpting to fine detail, you have full control over how your city takes shape.

A city is more than how it looks — it’s how it functions.

Plan and run an urban system supported by traffic simulation, economic systems, and data. Optimize flow, build supply chains, and use clear information panels to guide your decisions.

Start from a single road—and expand it into a functioning metropolis.

Freeform Road Systems — Design Without Limits

Every road you draw shapes how your city moves.

With fully flexible, grid-free tools, you can design any layout you imagine.

• No Grid Constraints

Draw roads freely—curves, highways, elevated bridges, and complex interchanges—without rigid limitations.

• From Country Roads to Megacities

Expand from quiet rural paths to dense urban networks, connecting every part of your city into a seamless system.

• Traffic That Responds to Your Design

Traffic flow is shaped by your infrastructure. Adjust layouts, reduce congestion, and keep your city moving efficiently.

Diverse Architecture — Define Your Own Style

Shape a city that reflects your vision with a rich architectural toolkit and full visual control.

• Build Across Cultures and Styles

Design anything from a classic American metropolis to a distinctly Chinese city, giving each district its own visual identity.

• True-to-Scale Landmark Buildings

Place iconic structures with accurate proportions and detailed materials—designed to hold up even at close range.

• Details That Reward Every Zoom

A large, high-quality asset library, supported by procedural generation, adds depth and variation across your city—from dense commercial areas to lived-in residential districts.

City Simulation — Run a Functional System

Every city runs on systems that need to be managed.

Take control of a complex city supported by transparent mechanics and real-time data.

• Balance Growth and Citizen Needs

Expand your city while managing housing, jobs, and essential services. Growth requires planning to stay sustainable.

• Build Realistic Supply Chains

Connect production, logistics, and consumption into a working economy. Efficient systems support stable development.

• Make Decisions with Real Data

Use clear data panels and visualized reports to understand your city—and make informed adjustments over time.
A Living World — Build at Scale

Your city is shaped by terrain, scale, and environment.

• A Massive Building Canvas

Expand from dense city centers to distant outskirts across a large-scale map—build a metropolis across a continuous landscape.

• Landscapes That Shape Your City

Plan coastal cities, mountain towns, and varied terrain where geography becomes both a creative tool and a planning consideration.

• Dynamic Weather and Lighting

Weather and lighting change over time, affecting how your city looks throughout the day and across conditions.

• Realistic Detail at Every Scale

From vegetation to building surfaces, details remain consistent as you zoom in and out.
