To install this mod you have to unzip its content into the directory

Far Cry 4/data_win32

The mod will overwrite 

patch_hd

and 

patch_hd.fat

so it is recommended to make backup of the two files.


The savegame needs to be copied into

C:\Program Files (x86)\Ubisoft\Ubisoft Game Launcher\savegames\eb0c5aec-e6a7-44c9-b233-27d8753d7417\856

The last two parts of the address may differ, 856 is the typical directory if you have bought the game via Steam.

Please make a backup of your existing savegame before you overwrite it. 

Since Ubisoft does only allow one savegame for FC4 it is recommended to make a new folder for each new save, something like 

"856 after end of act one"

With this method you can make as many game saves as you like.
