Fallout 4 Seasons is a mod created by GameDuchess and it adds various changes to the landscape.
Available through Nexus Mods, it adds all four seasons to the game and featured bright autumn foliage and plants, snow, plants and trees in hibernation for winter, crops in the spring and more.
GameDuchess used modern day Hiroshima, Nagasaki and Chernobyl as inspiration for the mod due to nature thriving in each area post nuclear devastation.
"Those places are extremely green and growing," GameDuchess explained, "with nature and animals there as much if not more than they were before the atomic bombs went off. And it's been far less than 200 years."
At present the mod won't automatically cycle through the seasons, so users will have to manually switch between them.
GameDuchess hopes to add this feature once the Fallout 4 Creation Kit is released.
