Microsoft has opened beta registration for the PC version of its upcoming game creation software Project Spark.
Windows 8 PC users can navigate their Internet Explorers to the following link and sign up for the beta here.
"Thank you for your interest in Project Spark!" an email will then tell you. "We'll be in touch as soon as information about our Beta Test is available. But wait, there's more! Zoom on over to the Project Spark Facebook Page to keep up to date with the latest developments."
The sandbox's beta version was originally due to reach PCs during October, with an Xbox One edition set for testing in January.
Due for a full release next year on PC, Xbox 360 and Xbox One, Project Spark will not need an Xbox Live Gold subscription to access - a change from Microsoft's previous stance on free-to-play releases.
Features exclusive to the Xbox One version will include Kinect-enabled performance capture, body animations, facial expressions and voice acting.
