Sniper Ghost Warrior 3 is a fun game with some design problems and technical issues. This mod aims to improve the game as much as possible.
This combined installer-based version of the mod replaces the previously separate distributions of UP/IP. Read the install instructions for more.
By "the root folder," you mean the folder it's installed, such as "C:\Program Files (x86)\Steam\steamapps\common\Sniper Ghost Warrior 3" correct? Sorry if it's a dumb question, I'm not good with terminology.
Yes. The installer will do some checks and warn you if it isn't installed in the correct location.
