Microsoft's free game-creation sandbox Project Spark will launch in beta for Xbox One in January 2014, the company has said.
It will follow a closed beta of Project Spark for Windows 8, due in late October.
Microsoft Studios exec Dave McCarthy told Digital Spy that the game will be largely complete by the time the Xbox One beta launches.
"Everything will be fully playable on day one [for Xbox One]," McCarthy said. "You'll be able to either use that Crossroads mode to build something really quickly through story choices.
"You can do the blank slate editor, or you can take games that other people have built and then just edit them for yourself."
The game's Xbox One edition will include exclusive Kinect features that allow you to record performance capture, body animations, facial expressions and voice acting.
An Xbox 360 version has also been announced.
