LOTS of stuff to destroy
Load the save and start bombing military bases / airports / refineries / oil rigs / ... EVERYTHING STILL STANDS!
Never understood why someone would need a 100% save with this game... If anything you need a save where u can destroy stuff wherever you go!
So here it is: The game is in mercenary-mode, meaning all stronghold- & agency-missions are done while keeping as much of the fragile landscape intact and ready to be blown up (16,67% overall completion). To achieve this without going crazy, I used a trainer to max out my money + chaos, so I could just skip all the individual faction missions (NONE of them are done). However, this caused a little bug, that prevented the "Extraction"-option from being enabled, so no free heli-teleports around the map; but theres LOTS of stuff to destroy on the way to make the journey enjoyable ;)
So there you are: Load the save and start blowing stuff up!
