This mod is a cave cover from Playerunknown's Battlegrounds (PUBG) from Sanhok map. All models do not replace anything, but are added as new ones. Textures taken from PUBG Mobile. The card has not been tested in SAMP and MTA, so there can be no guarantees.
You can find a cave near Santa Maria beach. The specific location can be found in the screenshots.
Installation: add files from the "gta3.img" folder to gta3.img using any editor; unzip the rest of the contents of the archive into the game directory.
