In Freeride Extreme go to the Works Quarter. Find the trolley turnaround(follow the yellow line if needed). Go south straight down to the end of the road. On the left you will see a large gray
building on the right will be a garage parking sign. Go down the alley until you see four stacked boxes. Get out of the car and on your left see a flower bed leading to a door. Walk up to the door and click the action button (right mouse on PC). Exit the game and when you play again Freeride Extreme will be on the menu. P.S. you may want to click on the red door and the steel door on the corner of the building just in case.
