The nuclear holocaust isn't too cool... maybe only in certain movies or video games like Fallout 4. And it isn't cool because it has to do with living in a grey sad world, where life as we know it nowadays wouldn't be possible.
Not everything has to be grey in a nuclear winter
However, some people think that an atomic apocalypse doesn't necessarily need to be so, as is the case of Nexus Mods Razed, that have developed a Fallout mod 4 that gives it an overhaul and plenty more color. It's called Enhanced Wasteland.
An apocalypse had never looked so good.
The purpose of this mod is to make the game's wasteland look much more lively, with an aspect that seems less worn out. In fact, certain settings seem to give the game a higher image quality.
To be able to make the most of this mod, you have to download these files, install them in the game's folder and run Fallout 4 as usual.
