So! Why does this have so many downvotes...

4587964 For one thing, the description said Fallout Equestria was "award winning". What award could it possibly win? Most Angsty Horsewords of 2012?

Judgning by tags and story description, main pony will find a human. But given that this is 15 years after S&R, it's not really the Fallout Equestria world we enjoy.

I would have to say because -

1. It's a Fallout: Equestria spinoff. People are sick of those.
2. The yawn inducing encyclopedia-style opening.
3. The fact that if you got past those paragraphs, it's incredibly difficult to tell what's going on.
4. Completely Random Capitalization.

You should work on the formatting. I don't mean your pacing or your paragraphs are bad or something like that, I mean you should do space lines instread of just indenting the next paragraph. This is in no way a book, you don't need to save costs by saving paper, nor do we have pages at all. We've got only one page, which should be spaced reasonable. Like that:

“Hit the deck!” I exclaim as I point it right at him. Taking the cue, he drops to his withers as I pull the trigger, the resounding clap of the discharge permeating the area. The merchant opens his eyes and looks up, wondering what just happened. He slowly turns around to look at the slimy half-decayed corpse behind him missing the right foreleg and neck up. “That much… Fucking Ghoul! Get down, guys, we need to take it quick and quiet from here if there are more of them, which means no more demonstrations or stories for now!” I growl in a low whisper. We take off full gallop from the area as red ticks start to converge on the location of the fired shot.

“Nopony, you’ve got the EFS, where are they coming from?” The lead merchant asked frantically as we got ourselves and our pack Brahmin behind the cover of crumbling cement highway barricades. I take a look around, the blips were tracking from the direction of a particular building, focusing on it, I could see them shuffling out.

“Looks like the sewer way-station,” I report.

“Figures, they’ve been hiding in the pipes for years, musta’ just crawled their ways out,” the rear merchant mutters as he raises a 10mm submachine gun.

Approaching the ruins wasn’t difficult, but I noticed a severe spike in magical radiation levels as I drew nearer, and that what had once been a humble home looked like it had been hit by a falling sky wagon. I was starting to put the pieces together; the radio broadcast was an advanced distress beacon from a fallen aircraft, probably Enclave. Ooooh boy, this was gonna be good!

I pop a tablet of Rad-X into my muzzle, and take off running towards the crater behind the house. Enclave tech was worth a shitload of caps, I’m practically salivating from the idea of what I’d get when I crested the rim of the crater… Then I stopped in my tracks, looking down at the wreckage. Sweet mother of Luna…

As for the points people might dislike about this story:
- the alien/human scene at the end. And your human tag in general. The first seems so out of place in this moment and the second is something not liked in FoE in general. I can't give you any advise apart from removing the humans, but I don't know how important they are to your story.

- your OC, Nopony Knows: you portry him as more than just overpowered, the only way he could be stronger is if he would be an alicorn. I mean, you say he's a scavenger. That's fine to most people. A scavenger who can protect himself, that's even better, but a scavenger

The Army taught me how to engage a superior force, ration supplies, shoot to kill, and rescue hostages,

and the worst thing is for some reason he's able to actually do all this. He's a scavenger, not a soldier. In one sentence you talk about his merchant barding and the next says he's "Lieutenant Nopony Knows". And with his 15 years (which is, taking the word of one of his fellow soldiers and the raider, still a kid's age) he's already lieutenant?

“Just give me the specs. The NCR needs ponies like me to do this, and if I die, I sacrificed myself to broaden the ideals of freedom, safety, and peace,”

I thought he was a trader!
- is there anypony even close to his skills with guns? I mean, he basicly takes that village on his own and when engaged by raiders he just stands there and kills all of them in a few eyeblinks.

while my rifle was far from pinpoint accurate with my posture, it hit home in the neck and eye sockets of the fourth Raider

While such things can be made (I did it myself in my story one time) it has to be for a reason, just not to make the MC look badass. If he would be a geneticly engineered super soldier or trained his entire life to become accurate like this that could be accepted, but you tell us basicly: "he's just that good"

The gravity of what warfare was couldn’t be drilled into you by an instructor or by stabbing a stitched dummy,

But exactly that happened to him.
- stuff like

I casually began looting the Raider remains, mostly crap and drugs, but crap and drugs I could sell to make up for the bullets I’d just expended. The last one lay on the curb, holding her mortal wound as it was slowly finishing her off, I cantered casually to her.

“Please… Don’t…. Kill me…” Her final plea for life struck me as insulting.

“I’m a soldier, what have you done for society, you fucking filth? Raped and murdered other Raiders? I’ll do you a favor…” I spoke heatedly through gritted teeth as I levitated her head to the concrete curb, opening her mouth and making her bite it, “And end your misery,” I muttered as I kicked down on the back of her head, splitting her jaw open, giving her body the final shock to kill her. A curb stomp; fitting given this battle’s outcome.

That whole talk about society and filth makes Nopony seem so arrogant and it sounds like a justification any of the "evil ones" (like terrorists or nazis in movies etc.) give to justify whatever they're doing . He disgusts me. I don't want to read about a character like this in first person. In 3rd person maybe because I wouldn't have to hear his thoughts all the time, but this?

- there are time-shifts in your narration, sometimes it's present tense, sometimes past tense. This shouldn't happen.

General advice: just make your character less overpowered and things should turn out better.

1. It's a Fallout: Equestria spinoff. People are sick of those.

Well, I wouldn't say that. There are still many spin-offs (and their number still grows and grows), most of which are quite successful. Of course not so successful like two years ago, but no indication of people being sick of it.

4587964 the problem is that this story is now stigmatized with the many downvotes. The story might not be terrible, but unless the author brings out a really amazing next chapter, the red stream will continue. Just because of the previous downvotes. Sadly it is like that.

I'm sorry, but this story is pretty bad.

Character is too OP, is arrogant, is fifteen years old and already a master of everything. He shows no remorse, no kindness for someone trying to fight the Good Fight. If anything, the OC is a terribad villain in the making.

Also, figure out what your character is before you start changing his profession as the story lurches along.

Fifteen dislikes and not a single like. That's a record
