This sound effect that I can use to my film trailer for example when the panic wreaks around the Vatican city of Italy I can use when people are running away from danger

This sound I can use to huge chaos in dramatic moments when people are fighting to survive

This sound effect is very good for my film trailer because when you can see lot of cars around the city and you can see how the car are destroyed by nature and fall into the abyss

This sound effect can be used when the car in my film trailer trying to turn left or right to speed up a car engine
