The only thing to keep in mind when modding XCOM 2 is that certain mods only work for certain versions of the game - though the descriptions and launcher will mostly keep you right. Showing their commitment to the community, Firaxis actually teamed up with Pavonis Interactive the creators of the original Long War mod for Enemy Unknown to make sure that the modding tools were as streamlined as they could be before releasing them into the wild. Firaxis are up on Bethesda levels of supporting the modding community these days and while they seem to have left the community to their own devices, they have made it so easy for modders to really change the whole game.
