Unity has announced that independent developers registered with ID@Xbox now have access to a free public preview of the Unity 4.3 Engine.

Unity announced this development on its website.

“The list of Xbox One features and API’s is extensive. While we have wrapped some core features directly inside of Unity, the vast majority of the platform specific functionality we are distributing with full source as an independent package of plugins. We believe this is the best way to empower you to extend these systems to fit your games’ needs while providing a core out of the box experience that will work for many games.

Writing native plugins and marshalling data from managed to native is not always straightforward and Xbox One has a high degree of asynchronous APIs. The native Plugins make it easier for developers to integrate the Microsoft APIs with Unity, providing constructs like the EventQueue to help with calling into Unity systems from asynchronous callbacks.”

Unity is powering games like Moon Studios’ Ori and the Blind Forest and Asteroid Base’s Lovers in Dangerous Spacetime.

Elsewhere in the announcement, it was confirmed that the next iteration of Unity for Xbox One will skip Unity 4.5 and go directly to Unity 5.0, but before that there are plans to upgrade Unity 4.3 in the meantime.
