INSTALLATION: Place the files in the "SurvivalsData" folder, make sure to remove the original survival files in the "Survivals" folder, and put the new ones in.
After that, you're good to go!

And for the survival maps, place those in the "Spooner" folder, which is in your menyooStuff folder, located in your GTA V directory. To have them placed is via the "Object Spooner" section in the menu.

Now enjoy causing havoc with these new survivals!
