Rare is running a competition to find the best user-created vehicles in Banjo-Kazooie: Nuts & Bolts and plans to incorporate them in the game.
All you have to do to get involved is take a screenshot of your vehicle (Pause menu, Photos & Replays, Take Photo) and then upload it (Photos & Replays, Open Photo Album, My Photos, select it and hit the Y button).
The closing date for submissions is 5th January at 8am GMT, and if you win Rare will get in touch directly via Xbox Live to get hold of your blueprints.
There's no word yet on just how your best contraptions will be immortalised in the game - whether it's by a title update, DLC, or whatever - and when we rang up Rare to find out we were told it's a big secret or at least nobody knew.
But apparently we can expect to find out more in the New Year.
