Since it’s a multiplayer game, you are playing in an arena full of opponents from all around the world. Try to pick up some bonus items and use them to destroy your opponents’ carts.
Also, be sure to avoid getting destroyed yourself. Your objective is to accumulate as many points as you can and thus get to the top of the scoreboard.
In the menu, you can pick between individual drivers and also customize the color of your cart. Call a friend and have fun together.
