Project Spark developer Team Dakota has announced that the game-building platform is now in open beta on Xbox One. The news was revealed on Major Nelson's blog.
Those looking to join the beta will no longer need a key to do so and to get started you'll need to search for Project Spark on the Xbox One store and install the game.
Some Xbox One beta players have complained of lighting issues but even so, there's a host of things you can get up to. Here, for instance, you can check out the opening of the first Fable remade in Project Spark.
