From the campaign:
You and your neighbours just won a unique collectible. First one to get there, claims the prize, but none of you have a car. Time to hitchhike!
In Carmarace, everyone on your block just won the chance to pick up a limited edition collectable at the convention being held on the other side of the continent. There is only one of these collectables up for grabs and the first person there gets it! The problem? None of you have a car…
As players hit the streets, sky, and tracks, they will hop into different vehicles with different “Karma”. You might get really lucky and have a nice open road in front of you… or you might get an old lady crossing he street, which can slow you down. In this race, what goes around comes around. You’ll run into speeding tickets, road blocks, jet fighters, trains, cars, planes, old ladies, etc.
So, hitchhikers, head out there, put your thumb up, and hope for the best!
