So ive been playing RF:G for a while now and have been getting used to demolishing everything in sight, and lately i kind of saw some structures i could have sworn i blew up that returned after not visiting them for a while. I don't want to play the game and at the end have to strt over cuz everything is gone. Is there a way to rebuild structures or maybe do they come back after some time? Plz help thx!

I think buildings that aren't marked as targets on your map come back eventually if you destroy them.  Anything that your map says to blow up shouldn't come back, and if it does don't worry, you already got the morale and lowered EDF control the first time you did it.

Can you complain about building reconstructing?  It means you get to blow them up again, and I think we can all agree that Red Faction Guerrilla does that pretty well.  = D
