If you’re at all interested in MotorStorm, then you might want to read this article about the game. They discuss a few interesting things. For one, there’s going to be seven different vehicle types, with 5 vehicles in each group. As well, environments are somewhat destructible, because it’s possible to ruin a ramp for further use, thus forcing you to take a different path.
As well, the tracks behave differently each time you pass over them, because you change them from run to run. And as you drive those tracks, you’ll also have to watch out for your fellow drivers, because they’re tring to add some character to your opponents. What kind of character? The kind that’ll try to run you off the road – that kind!
[Edit: Ooops, I forgot to mention. You’ll be able to use your own music in the game! Great!]
