single-player races can turn into multiplayer pursuits
EA showcased the open world of Need for Speed Rivals, where players can suddenly join races that can turn into pursuits -- with both the cops and the racers being controlled by players. With the All Drive mechanic, a single-player race can be transformed into a multiplayer experience. Ghost Games described it as a "non-stop racing experience."
Rivals is coming out for PS3, Xbox 360, PC, Xbox One, and PS4 later this year.
