Complete 1000 sabotages.
Throughout the game the main objective is to cause chaos & the main way to cause chaos is by blowing things up. The objects you are looking for are government property and the colours that help you identify this property is red & white. Also look for a white star on the objects. There are a different number of ways to sabotage the objects, the easiest and quickest of which involve:

- Shooting them with the fully upgraded assault rifle
- Using C4/grenades
- Other explosive weapons i.e. rocket launchers, AA Guns
- Using any helicopter with a machine gun/rocket launchers. The helicopter is the fastest and most effective, especially as you will have infinite ammo.
This wont come as you progress through the game. You will need to do alot of side missions & complete locations to get the 1000 sabotages needed, see the Freeroamer 2 trophy for more info. I have a made list of destroyable objects and how many are needed for each:
