JulioNIB included a note stating that this mod, like the rest of his Grand Theft Auto V mods, requires two plugins to work: ScripthookVDotNet and ScripthookV & ASI loader.

JulioNIB has also made a few updates to the mod to fix certain issues, including some bugs related to the weapon wheel, certain controller problems, and adding support for hotkeys, which are listed in the mod’s blog post.

This mod appears to be a follow-up to a similar one JulioNIB made for Grand Theft Auto IV though, of course, many of the features are different. Both mods are available for free to anyone who feels a mighty need to combine either Grand Theft Auto game with Watch-Dogs.
