The closed beta test for Xbox One game-builder Project Spark will begin in February, Microsoft has confirmed.

Access to the beta will be limited to selected individuals, but if you've already gotten yourself a key for the Windows 8 beta, you'll automatically be given access to the Xbox One beta when it starts.

And don't worry if you've already given your Windows 8 key away: Microsoft will be sending a second key to everyone when the Xbox One beta begins.

If you've yet to sign up for the beta, you can do so here.

Project Spark provides players with the tools to create their own games and experiences, and share them online with other players. The full game is expected to roll out later this year.
