Larian Studios Forums Divinity: Original Sin 2 - The Modding Dungeon Divinity - Original Sin 2 - Modding Scripting where are the game scripts located?

Yeah, they need to be extracted. You can find information on the tool here at the wiki. I actually don't know which PAK file exactly that you'll need since I have not edited the gameScript file myself, but the PAK files are located in the install path\Data directory.
