This mod was original made by jo2dev http://www.gtagarage.com/mods/show.php?id=9342. I loved it and I thougth I could modify it. jo2dev gave me permission to publish my modification and here you have it.
My modifications includes: do you remember the cheat EVERYONEISRICH ? all the cars that appears when that cheat is activated are now on a parking lot inside the base.
Hunter replaced by Hydra, a new helipad in the floor of the parking lot and some surprises there. I hope you enjoy it.
Main credits go to jo2dev, for his great mod.
