Red Faction: Guerrilla

Easiest way to do this is to play through the game until you unlock Eos Sector. Then, repeatedly do the side mission with Jenkins where you destroy EDF property in the gunner seat. You can play that side mission indefinitely. Should get around 80-90 million in EDF property damage every time you play the side activity.

Jenkin's Missions really help with this; some of the later ones give over 80 million credits of damage. And if you do not feel like doing something repetitive, mess around, have some fun! Remember, when you get in red alert later in the game, Edf fliers will attack you; Edf fliers are easy to destroy with the heat-seeking rockets or if you feel skilled, the nano rifle. Each flier nets you about 5 million credits of damage, and the damage adds up fast.

On last mission in massive tank kill everything up to when you see the marauders then die and repeat its how i got it and it was pretty fast

This isn't really a solution but I know a way to cause destruction infinitely. The way is called walkers and tanks. I don't know where light and heavy walkers spwan but I know where combat walkers start. They spawn at the garage in the sector Eos. As long as you don't blow up the garage there the walker will ALWAYS spawn. Its near the middle of the secotr just North of the Martion Councel. The garage is a medium importance target. For people earlier in the game there is a garage at Dust that works the same way. Only its a tank and there are more guards around it but its lots of fun.
