Criterion has just released the v1.6 update for Burnout Paradise! This may, by far, be the biggest non-DLC update yet. The update includes an in-game store, an in-game website, the ability to restart offline events, improved vehicle dynamics and finally, easier barrel rolls.
For people who will be getting the Ultimate Box edition tomorrow, this update is already included.
Pictured below is an image of what the Burnout store will turn out to be.
