Unity 3d V3-3 [Intel/KG].

Unity is an integrated authoring tool for creating 3D video games or other interactive content such as architectural visualizations or real-time 3D animations. Unity is similar to Director, Blender game engine, Virtools or Torque Game Builder in the sense that an integrated graphical environment is the primary method of development.
The editor runs on Windows and Mac OS X and can produce games for Windows, Mac, Wii[1], iPad, or iPhone[2] platforms. It can also produce browser games that use the Unity web player plugin, supported on Mac and Windows. The web player is also used for deployment as Mac widgets. Support for Xbox 360 and PlayStation 3 have recently been added.

Unity won the Wall Street Journal 2010 Technology Innovation Award in the software category [3]. In 2009, Unity Technologies was named one of Gamasutra's "Top 5 Game Companies of 2009" [4] for Unity. Unity was a runner-up in the Best OS X Graphics category in the 2006 Apple Design Awards [5].
