Since Project Spark was announced at E3 in June, hundreds of thousands of fans have signed up for the closed beta, which has begun rolling out today. Starting exclusively on Windows 8.1 and available to fans on Xbox One early next calendar year, registered beta participants are welcomed to a dynamic community where players create and creators play. The beta for both platforms will continue until the product launch next year.

Project Spark is an endless adventure where everything is customizable. Jump into an open world sandbox where players can create their own games, movies, stories and more and then share them with family, friends, and the world.

• Play what other creators have made and take part in unlimited adventures.
• Make games while playing with the revolutionary Crossroads mode.
• Bend, shape, and mold worlds with sculpting and beautifying creations with paints and biomes.
• Master the easy to use brain system to add behaviors to anything and bring creations to life.
