Urban Construction Simulation Game Unity Source Code

Players start with bare land and a budget that barely covers a road. Zone plots, drop buildings, collect income, turn nothing into a functioning city. Complete Unity source code, Android and iOS both. Buy it, reskin it, publish it.

What Is an Urban Construction Game?

Early levels feel open. Wide plots, low costs, room to experiment. A few levels in the grid tighten. Budget ceilings drop. A residential block needs roads before it generates income. A commercial tower needs nearby residents, or it sits empty. Wrong placements do not punish you outright; they just slow your money. That friction keeps players thinking without making them quit.

The upgrade path drives session length. A basic house becomes a mid-rise, then a high-rise, each tier visually distinct and more profitable. Players watch the city change. That visible progress is why city builders have some of the strongest daily return rates in casual mobile.

Key Features

These features were verified directly from the source code and confirmed through full gameplay:

• Tap-to-Place Building System — Tap any valid grid cell, pick a structure from the build panel, and it snaps into place. Zone validation runs automatically with clear visual feedback before every placement.
• Progressive Level Structure — Multiple levels ship pre-built, each tighter than the last. New building types unlock per level. No level design work required from the buyer.
• AdMob Banner and Interstitial Integration — Both placements coded and tested. Banners on the main menu, interstitials at level completion. Add App ID and unit IDs in one script — revenue starts from the first install.
• In-App Purchases — Coin packs and ad-free upgrade implemented through Unity IAP. Purchase and restore flows both work. Update SKUs, and it is live.
• Firebase Analytics — Session length, level completions, resource events, and purchase triggers all fire automatically. Data in your console from day one.
• Single Codebase for Both Platforms — One Unity project. Android and iOS builds both come out clean with no platform-specific rewrites.
• Tap, Drag, and Pinch-Zoom Controls — Tap to place, drag to pan, pinch to zoom. Calibrated for phones between 5 and 7 inches. One-handed operable throughout.
• Building Upgrade System — Every structure has upgrade tiers. Each tier increases output and changes the building visually. Players spend coins, see the result immediately, and want to go again.
• Three-Resource Economy — Coins, population, and happiness run independently. Each building type affects all three differently. Real tradeoffs, not just place-the-most-expensive-thing.
• Pre-Built UI Screens — Level select, score summary, and local leaderboard are included and functional. Nothing to build before submission.
• Ready to Publish — Opens clean in Unity 2021 LTS. No missing references, no compiler errors. Submit to both stores without fixing anything first.

Controls

Tap an empty cell to open the build menu. Select a structure and confirm. Drag two fingers to the pan. Pinch to zoom. Tap any placed building to check stats or start an upgrade.

No virtual joystick. No tutorial popups are blocking the screen. A first-time player figures it out in thirty seconds.

Developer Perspective

• Full Unity 2021 LTS Project — Every scene, script, prefab, sprite, audio clip, and config file included. Nothing missing.
• Clean Commented Code — Systems separated. Building placement logic does not bleed into economic logic. Function-level comments throughout. Anyone can read this codebase cold.
• Grid and Placement Pre-Built — Snapping, zone validation, and occupancy tracking all done. You are not rebuilding this.
• Economy Tuning via ScriptableObjects — Coin rates, upgrade costs, and balance values in ScriptableObjects. Change numbers in the editor without touching scripts.
• AdMob Fully Wired — Two values to update. App ID and unit IDs. Everything else is already coded.
• IAP Fully Wired — Unity IAP configured. Update product IDs to match your listings. Purchase the screen and restore the flow work immediately.
• Firebase Drop-In Ready — Add google-services.json. Analytics fires automatically from that point.
• Reskin Without Scripting — Sprites organized by building type. UI colors from a central palette. Basic Unity editor knowledge handles the full reskin.
• Tested. No Known Bugs — Ran on physical Android and iOS devices. Ads work. Purchases complete. No crashes in normal play.

Reskin and Rebranding Options

The grid and economy are theme-neutral. The same codebase becomes a medieval village, sci-fi colony, fantasy kingdom, or beach resort. Swap the sprites, rename the buildings, and players never know it started as an urban construction game.

What you keep: grid logic, economy math, ad placements, IAP flow, Firebase events. What you replace: every visual asset, UI text, sound effects, and color theme.

No shaders to rewrite. No procedural generation to understand. Basic Unity editor skills are enough.
