The latest version of Unity Technologies' Unity development platform, version 2.5, will add support for Windows Vista, XP and 2000 -- promising "100 percent feature parity" with Mac OS X. The current edition of Unity supports browser games, iPhone and Wii titles. The company says Unity 2.5 has been rebuilt so that it functions identically with both Mac and Windows, with the same engine underneath. Notably, Unity Technologies says version 2.5 will feature cross-platform interoperability -- developers can create Windows games using the Mac platform and vice versa. Unity 2.5 has also optimized its toolset with the intention of increasing ease of use, implementing a tabbed interface and new flythrough controls. Information like mesh rendering stats and audio clip waveforms can be retrieved "at a glance." It also adds drag-and-drop 3ds Max support to its existing support for Maya, Blender and other 3D apps. "Starting today, Windows users can finally get their hands on our tech which has been used to create dozens of hit games and is being used by thousands of developers on the Mac," says CEO David Helgason. "We have huge expectations of how far we and our community can go."
