Unity is a multiplatform game development tool, designed from the start to ease creation. A fully integrated professional application, Unity just happens to contain the most powerful engine of graphical design.
1. Integrated Editor:
The Unity game engine is happily married to the Unity development environment. This tight integration allows the Editor to do everything a published game can do. The simple, visual, and intuitive nature of the Editor makes building games fun again.
2. Graphical Power:
Unity has a highly optimized graphics pipeline for both DirectX and OpenGL. Animated meshes, particle systems, advanced lighting and shadows, all will run blazing fast.
3. Asset Importing:
Unity's Asset Pipeline is Unmatched. All major tools and file formats are supported, any art application can be used with Unity.
4. One-Click Deployment:
Unity supports a wide range of publishing platforms, all available at the push of a single button.
5. Wii Publishing
The Wii console is all about new types of games and new ways to play. Unity embodies that philosophy with an Editor that's built around creating game play. It's never been quicker or easier to modify and iterate your game's functionality.
6. iPhone and iPad Development
Whether on an iPhone, an iPod touch, or an iPad, you will be able to dazzle your audience with the finest content available in the App Store. 2D or 3D, touch or tilt - if you can think it, you will be able to build it.
Unity's shader system combines ease of use, flexibility and performance. All the built-in shaders integrate perfectly with any type of light, with cookies or without. If that's not enough you can write your own shaders in Unity's powerful ShaderLab language with Cg and GLSL.
Vast, densely foliaged landscapes that work smooth on low-end hardware. All that and they take up almost no disk space.
Take your single-player game and easily bring it online. Add some online high scores and chat. Create real-time networked multiplayer functionality. Unity supports all networking needs out of the box with little learning and even less effort.
Give your GameObjects life with the built-in NVIDIA PhysX Physics Engine. It's the world's most advanced physics engine and is used in games like Batman: Arkham Asylum and Mirror's Edge.
11. Audio & Video:
Mix realtime 3D graphics with streamed audio and video.
13. Unity Asset Server:
The essence of game development is multi-disciplinary collaboration. The Unity Asset Server is an add-on product which adds version control to Unity.
14. Shadow & Light:
Unity's provides a highly optimized lighting system with realtime shadows and baked lightmaps. Use shadow and light to great effect, without worrying about the gritty technical details.
