Banjo-Kazooie 3 is to be suffixed Nuts & Bolts and will let you dynamically build vehicles as you collect parts around each level.
That's according to the increasingly famous poster called SolidSnakex on NeoGAF who has listed the entire contents of an upcoming Game Informer preview. Rare declined to comment.
Banjo-Kazooe 3 is Xbox 360 exclusive and is said to be among the first Rare projects to be solely developed for the platform from the outset.
Because of this, Rare wanted more than a high-resolution Banjo platformer, although despite the large vehicle focus there will still be plenty of platform elements like tight-rope walking and "jiggy" piece collecting.
An example of the vehicle tinkering given in the Game Informer piece was a four-wheeled kart with a spring attached on the bottom that allowed it to hop over things. This later had a helicopter blade added that enabled it to fly. Then it had balloons added and the helicopter blade put on the back to make it work like a hovercraft.
There was also a monster truck vehicle that detached its chassis to become a mini-bike which, when launched off a cliff, stretched out its collapsible glider wings and started flying.
Rare is apparently aiming at around 1600 collectible parts and weapons with which to customise your rides. You'll have to collect notes to act as currency so you can buy vehicle blueprints.
The main area will be Showdown Town that is apparently 16 times bigger than anything Rare has made before.
Each of the six different levels will have a unique introduction, such as a spoof of an '80s soap opera, and there are around 15 challenges and side-missions spread across them to keep things fresh.
Banjo-Kazooie: Nuts & Bolts is due out this Christmas period.
Pop over to the leaked Banjo-Kazooie: Nuts & Bolts screenshots to find out more. And remember, it is definitely not a racer.
