Overgrowth, Immersive Living Forests and Grasslands
Like some of the other mods listed here, Overgrowth adds a ton of greenery to the Commonwealth. The mod adds green trees, bushes and grass and it does so without taking up a ton of space on your hard drive.
Unlike some of the other mods listed here, Overgrowth is extremely small for both the PS4 and Xbox One. We're talking 6.8MB small. That's tiny.
Fortunately, the mod packs a huge punch and you can get a feel for the changes in the walkthrough video below.
