Can I use XCOM 2's modding tools to create my own mods?
XCOM 2's modding tools are not compatible with the Mac or Linux versions of the game.
On Windows, XCOM 2's provided modding tools are an extension of Visual Studio, Microsoft's proprietary integrated development environment (IDE). At present, Visual Studio is only available on Windows, meaning XCOM 2's modding tools are not available on other platforms.
If you own the Steam version of the game, you can still download and use mods using the Mod Manager. See How do I use mods in the Steam version of XCOM 2 for Mac? for more details.
