Highway Racer 3D Car Unity Racing Game Full Code

Highway Racer 3D is an endless highway racing game built for mobile. The player drives through heavy traffic, collects coins, dodges vehicles, and earns enough to unlock new cars. Three road environments come included — a standard daytime highway, a night road, and a rain environment — each delivering a different visual challenge on the same core racing mechanic.

Complete Unity source code. Android and iOS included. Buy it, reskin it, publish it.

What Is Highway Racer 3D?

Endless highway. Traffic ahead. Coins to collect. Cars to unlock.

The player drives forward through continuous traffic, steering left and right to avoid collisions. Every close overtake earns coins. Every coin earned goes toward the car unlock system; new vehicles with better performance are available as the coin balance grows. Three road environments unlock progressively: the simple daytime road first, the night road second, and the rain road third. Each new environment introduces different visual conditions that change how the road reads at high speed.

The run ends on collision. The retry is instant. The coin balance carries across sessions; players return specifically to finish unlocking the next car.

Key Features

• 3 Road Environments — daytime highway, night road, and rain road all included, each with distinct lighting and visual atmosphere, environments unlock progressively as the player advances
• Coin Collection System — coins appear across all three road environments during the run, collected coins accumulate across sessions, and fund the car unlock system
• Car Unlock System — multiple cars locked at start, unlocked by spending collected coins; each new car offers different performance characteristics
• Endless Highway Mechanic — road generates continuously, traffic density and speed increase as the run extends, no defined endpoint
• Traffic Dodge Scoring — close overtakes earn bonus coins and score multipliers, risk-reward mechanic rewards aggressive driving without direct collision
• Multiple Traffic Vehicles — cars, trucks, buses, and SUVs populate all three road environments, varied traffic types keep the dodge mechanic unpredictable
• AdMob Integrated — banner ads, interstitial ads, and rewarded video ads pre-configured, update publisher ID, and monetization is live from day one
• Android and iOS Support — single Unity codebase, build for both platforms independently
• Ready to Publish — stable, tested, production-ready for store submission

Controls

Built for mobile one-handed play.

• Tilt or touch — tilt the device to steer or use the left and right touch zones; both control options are available
• Brake button — dedicated brake input slows the vehicle, useful for tight traffic gaps at high speed

Simple two-input system: steer and brake. No complex gestures. Any player picks it up in the first thirty seconds.
