According to the official Facebook page, the Project Spark beta will be available on Xbox One in February.
“Project Spark Xbox One closed beta begins in February. If you have a Windows 8 beta key, it will also give you access to the Xbox One beta.”
Project Spark allows players to create game worlds using a user-friendly set of development tools. Projects made on the PC version will also be accessible on Xbox One.
We’ve had a chance to demo the Windows version and I can say I’m really excited to play around with it on the Xbox One. The tool set will probably be somewhat limited in the beta but it already seems that the creative potential for this is unlimited.
