Press Play, the game studio behind the Xbox LIVE games Tentacles (our review) and Max & the Magic Marker (our review), has released a beta version of their Unity porting toolkit (Fast Forward - FFWD) for Windows Phone developers who wish to port across a Unity game engine developed title to the mobile platform.
"The framework has been used for creating the games Max and the Magic Marker and Tentacles for Windows Phone 7, and is currently being used by another project at Press Play."
Developers will be able to use this toolkit (released under the MS-PL license) to export assets in the Unity editor. Full 3D support is present for graphics, but physics are limited to the 2D Farseer Engine. What's great about the toolkit is that it enables developers to do most of the work in Unity 3D and then port it to XNA.
Head on over to GitHub to download FFWD and be sure to check out the wiki.
