Unfortunately I personally /can't/ play the fallout games... The ability to get around in the game is beyond my skills?
But... i watch my girlfriend/roommate/Domme so I'm Very familiar ?
Yeah DUST...
Fallout 4 though is my fave ?
Zion in Dust...Jesus fucking Christ I remember my first time going there. Almost instantly I felt uneasy, like something was watching me, it was dark as all fuck, but I pressed on, came upon a bloodstained scroll that read out "The Walls Speak True. The Tall One. The Branch Fingers. He Hunts. He Finds. He Kills. The Walls Speak True. The Walls Speak True. The Walls Speak True.", Put down my pipboy after reading and heard a inhuman growl/hiss/wail. And I instantly hightailed back to the Mojave, not wanting to find out who "the branch fingers" was. A few months later Al ChestBreach made it to Zion, so I decided to watch him and see what was in Zion, a Wendigo, supposedly Joshua Graham reincarnated. And when I say dark, I'm not over doing it, it is incredibly dark in Zion, 24/7 basically

And when the Wendigo spawns in you better pray you have Project Nevada installed, because you'll need it to RUN, like the NES Godzilla RED creepypasta. You can't fight the wendigo, you just need to run and hope it decides to spare you for the next 15 or so minutes. And believe me, it is very dangerous and tall (about as tall as a watchtower I'm pretty sure) you can still injure it, but I'd advise against it. It has an incredibly high health level and since it's DUST you for sure wouldn't have enough ammo to spare, and even if you do he'll just respawn eventually. It's best to just run and hide until he goes away, and save your ammo for other things. It may not look like much. But in the pitch black canyons of the once bright and beautiful Zion it can be truly terrifying, because you get no warning other than a shreek mixed with a scream mixed with a wail when we spawns in...

The mod though is still amazing. More amazing than New California and the upcoming Miami for Fo4, those are just one big worlds, but DUST changes the base map, Zion, Big MT, Sierra Madre, and The Divide. It alone is kinda lackluster, but in combination with the interior adding mods, Project Nevada and Project Solid,the mod that adds in Bunkers everywhere (forgot it's name) and some others. (Bunkers is good because they will have plenty of drinks and food, a bed, etc which if you're playing DUST with survival mode enabled will be a lifesaver.
