Rampage missions require you to smash objects, and achieve a target score in Euros.

All rampage missions have a bonus object, such as a lamp post or a stop light, which can be smashed to add to a bonus multiplier. This multiplier can be raised to a maximum of 8x. The object for the current mission can be seen in your HUD.

Target these bonus objects prior to anything else when starting these missions. A full bonus multiplier is key to achieveing the top ranks. Then aim for high value objects, or clusters of mid value objects.

High value objects include the vendor stands, bus stands, parking meters, ATMs, or destructable buildings (guardhouses or large vendor stands). Mid value objects include pottery stands, benches, or cafe seating.

I'd recommend using a mid-sized car with good handling for these missions. An 'A' or 'S' rating will unlock a new Rampage mission, as well as increasing the melee damage of your car.
