Want to spice up Fallout 4's environment without having to download a 500MB+ file? Try RustBelt Flora from Spiffyskytrooper.
RustBelt Flora is a mod inspired by the fall and early winters in Canada and in the American Rust Belt (a region that stretches from the Great Lakes to the upper Midwest States). Boston, and thus the Commonwealth, is part of the Rust Belt.
This 47MB file is an extremely simple overhaul that gives the game's foliage a nice brown color. It's easy on the eyes and it doesn't feel out of place like some of the other overhaul mods.
The video above will give you an excellent look at what you can expect from the mod after you install it on your Xbox One. There's no PS4 version.
