well banjo kazooie is a game about a bear and a bird that pretty much fight evil. there is a evil witch named grunty..(i call her Jar-Head in nuts and bolts) and in the first banjo they defeat jarhead and then theres banjo kazooie 2 and they had another adventure to try to defeat grunty... now theres banjo kazooie nuts and bolts. it is totally different from the other banjo kazooie games but i think it is one of the best yet.
In banjo kazooie nuts and bolts u are yet again the bear (banjo) and the bird (Kazooie) and u are in a wild adventure of defeating grunty (Jar-Head) and her wild games.
u start out in showdown town which is ur hometown. so what they did is by adding nuts and bolts u kinda can guess whats its about. (i guess) well ya u get to Build YOUR VERY OWN CARs/PLANES/Boats/ and multi things... u could have a flying boat as a example..
one thing i forgot to say is that in all banjo kazooie games there are jigjaw pieces that u must collect. and its the same in nuts and bolts.u have to do quests kind and get a certain time to get a jiggy..(u go to other worlds to do quests) so u build ur own machines to complete the quests and then u put them in ur bank.
the next thing u must worry about is crates. without crates u can't really build ur own car so all around showdown town u will find crates everywhere.and inside them will be new parts.
check youtube they will hae lots of vids of it..
