Ahh this game brings back memories of smashing friends into the ground.
There's like 40-50 different bikers to choose from and they range from bad-boy to bad-girl or racer to racer girl. It doesn't really matter which character you pick it's just nice to have such a big selection. There is even one suspicious racer that not a girl but not a guy either...hmmm. Their attacks include hitting, smashing and sticking your weapon in their spokes and making them flip over.
The bikes come in two types. Speed or power. Speed obviously is faster but gives your character less stronger weapons. Despite this, speed bikes always cost the most. And power bikes are pretty much choppers and I shouldn't have to explain them as they are the exact opposite as speed bikes.
The stages (on career mode) are just open road way often with a lot of turns and cars but power ups too. There are stages for multiplayer that are a lot different with something ranging from huge jumps too if you don't turn right you'll either hit something or fall off the edge. There is a figure eight track too but that's boring.
As for the things you can unlock there is a lot but I don't want to spoil anything like a *cough*spoiler*cough* police motorcycles.
And so in all for a game that makes up for a somewhat boring career mode, it gets a 8.5 out of 10.
