I have updated again, I forgot to change the Chaos levels needed to unlock the Agency stuff. I have corrected that. So now as soon as you unlock the black market you unlock everything.
I have updated for those who had problems upgrading the agency vehicles.
I have refined and shrunk the size of the black market mod, it has all the pictures and everything from azam8, and maxovitsj on the Eidos forums just in a smaller package for quicker loading times in the black market. This has all vehicles and guns unlocked including Baby Panay's Rocket launcher, and the Bubble Blaster
Don't upgrade the added cars, only the agency stuff the others will just be wasting your money.
For those that are having troubles installing, you have to extract the 2 files x_buzz and x_buzz.tab to the archives_win32 which should be at a path like: C:\Program Files (x86)\Steam\steamapps\common\Just Cause 2\archives_win32 if you are not seeing any new vehicles in the black market you are not doing it right
For those complaining about these not being all the cars, you have to realize a couple things, one is that some cars share the same values and are just spawn random versions of the same vehicle, like the Agriboss has like 3 different versions all spawned by the same item number so i cant make separate versions for each. The other thing is some vehicles are either situationally spawned or only exists in certain locations like the MV Command, and the Fending EC2 Lift.
***Make sure you are putting this in the archives_win32 folder, and other mods into the dropzone folder. because if you have 2 files modifying the same values in the same folder it will only load the first file in that folder. if you have this in the archives_win32 and the other mods in the dropzone then it loads this first and then loads the changes from files in the dropzone folder.
