A uniquely extendible tool

Thanks to Unity’s carefully designed APIs and the generosity, creativity and professionalism of the Unity community, it’s improbably easy to extend the Unity engine in more ways than you’d ever have imagined.

Extend the editor yourself, or choose from over 1700 free and paid extensions on the Unity Asset Store.

Create highly-optimized content

Use Unity’s tools to deliver reliable performance, smooth framerate and superb player experience across target platforms. Create games that perform better at runtime, reduce graphics bottlenecks and take control of asset loading.

Amazing visual fidelity, rendering power and ambience

Make your game look just how you envisaged it with Real-time Global Illumination and our physically-based shader. From luminous day, to the gaudy glow of neon signs at night; from sunshafts, to dimly lit midnight streets and shadowy tunnels – create an evocative dynamic game to enthrall players on any platform.

Rapid iteration

Unity’s Play Mode is an incredibly powerful development tool for rapid iterative editing. Press Play and instantly you are inside your game, playing and previewing how it will look in its platform-specific final build. Pause it, and alter values, assets, scripts and other properties, and instantly see the results. And, you can step through your game frame by frame for easy debugging.

Unmatched import pipeline

Just drop your assets into Unity and they’ll import automatically.
