One of the best games I've played, especially in recent years. And it's a mod for Fallout 4, ALL MADE BY VOULENTEERS! Absolutely near AAA quality!
The map is gorgeous, full of new weapons, armors, completely new textures and models all over the place! The team deserves serious props for taking something like this on. I got over 80 hours worth out of this mod and it was 100% worth it.
The only reason that I didn't give this 5 stars is because it is still quite buggy. You will crash a lot, and some sidequests are going to require you messing around with the developer console, but the rest of what works makes it pushing through it 100% worth it.
Give it a try, IT'S FREE!!!!!
