Equestria has seen their fair share of dangers and threats made to their land by gigantic monsters and power-crazy lunatics. From all of these threats, the Elements of Harmony have been at the ready to combat them through the unbreakable bonds of the magic of friendship.

However, a new enemy bearing incredibly lethal weapons threatens to leave the Elements helpless against unprecedented violence. When one Element and two others are taken hostage, a group of elite soldiers contact Princess Celestia to offer assistance. They're professional and more than capable, but Celestia fears they may have ulterior motives. Not to mention, there's the fact that they come from another world.

Some say reality and the physical world are tied into a series of strings. That space and time are woven into an unbreachable fabric, a thick sheet that separates an unthinkable amount of worlds and realities. None of this is true, yet at the same time, it is. With a little influence and the right amount of force and energy, holes can be created, passages through which one may slip through. This isn't the only way, however. There are other ways. Naturally occurring tears and rifts that fit perfectly in the order of the universe.

The Battle of the Western Coast has been over for years now .Treaties have been signed and alliances formed, but the land has fallen into a restless peace. Trouble brews in Equestria. While most of the Lotkin tribes have settled on land granted to them by The Royal Sisters, renegade bands still roam the land, driven by some unknown force.

A fighting legend, a leader and the founder of Equestria's elite Royal Special Tasks Group has disappeared without a trace. His legacy is carried on by those he trusted most, running and expanding the unit he started, but can they continue without the experience and guidance he provided?

Another may have arrived to help. A man on a continuous search for his lost brother-in-arms stumbles onto the path his friend had previously walked, quite by accident. With luck, he may find what he was looking for.

This is a sequel to the first. If you don't read the first, you wont understand half of it.

From after-war status report on SPARTAN-IIs

Name:Lieutenant Kelsey-090

She goes by Ghost. The white unicorn mare is a legend. Nopony under her protection has failed to come back unharmed. A great shot with a set of impressive power armour, she is the last thing many raiders see.

But what they don't know is that Ghost is nothing but a bit of illusion and trickery. A front for my true form. My name is Kelsey-090. This is my story.

Little bit I wrote to get out some writers block. Just came to me when I was reading Fallout: Equestria. "Let's chuck in a SPARTAN to kick ass and take names! What the hell, why not!" So boom, have some human/SPARTAN in (Fallout) Equestria!

Also gore tag because fallout. Nuff' said

The Crystal War. A battle so long and brutal that it has shaped an entire era of righteous bloodshed. Ponies don't have slumber parties, or read bedtime stories to their foals, or even so much as smile. And when they do smile, it's the kind of smile that would keep ponies of a more peaceful era awake for days.

The madness of Sombra and his slave army claims lives every day. Soldiers in service to Celestia fight tirelessly to hold onto even a shred of what Equestria used to be. Its citizens do everything they can to feed the bloody machine, from canning food to holding funerals.

And at the heart of it all, there stand three mighty warriors. They have lost a great deal to this war, though none of them know just how much. What they do know is that they made promises back home, and they are not in the habit of breaking promises. No matter the cost.

This is the story of Iron Wing and the Demolition Crew.

As one life comes to an end, another life begins anew in a vast, strange world, full of the most magnificent wonders and the greatest terrors. Every twist and turn brings new experiences, bizarre friends, powerful enemies, and adventure as far as the eye can see. Whatever awaits this young man, he must be ready to face it with everything he has, lest he be trapped in this world forever, never to see his home again.

Equestria is less than a memory here. There is no magic, only enormous overpopulated Gigapoleis and miracles of genetic engineering. Living creatures are being constructed and programmed, shaped and modified, enslaved and abused. This is Earth. The indifference of its people is surpassed only by their greed and cruelty. Their kindness, honesty, loyalty, and generosity are too often just words. Their laughter too often means someone’s suffering.

But while friendship stands, any evil can be brought down, right? Right?

This work is a translation of a story "Сломанная Игрушка".

The project also features bonus content, among which is the audiobook version of the story and illustrations. All of it may be found here.

Billions of years ago, an underground bunker was created to protect Humanity from their destruction, but only one made it in before Oblivion claimed him. Now the AI that he awoke remains, one that has faithfully kept the promise he made to his father, waiting for someone, or something, to find him.

Note: This story's from the point of view of the AI (3rd person limited). As such, if he doesn't think that a detail is important it's probably not going to be mentioned. That's my excuse and I'm sticking to it!

As usual, comments go into the comment section (that's what it's for).

If you think the story needs a new tag, let me know which one and I'll consider it (chances are that I'll add it).

Holy shit. 100 likes. I... I honestly never thought that I would get this far... I can't all of you enough.

When a young human super-soldier falls to Equestria, he must move on from his dark past filled with war, tragedy and bloodshed. Will he embrace this new chance at life, this new beginning? And most importantly. can he protect it when an ancient evil returns for a second time?

(NOT a Halo crossover.)

!!!Due to an incredibly busy schedule now that exams for college entry are closing in, New Beginnings is on Hiatus!!!

A scientist is tasked with finding a way off of a dying Earth. Pollution took its toll on our planet, and now we have to face it's consequences. He finds a solution, rumoured to be capable of world-travel. He ends up in an unknown world, but one that is somehow strangely familiar...

:EDIT: This story, previously named The Riftwalker, is now this. The 'new' Riftwalker will be the story that continues from chapter 14 onwards, as to reduce confusion. This story will be marked as complete, and the chapters from 13 onwards will be moved to the new Riftwalker.

This story is a sequel to A Scientific Breakthrough

Unstatisfied with his current role in Equestria, Primal Dagger creates a new initiative: The Riftwalkers. He, along with Twilight Sparkle and a pacified Nightmare Moon set out to explore new worlds using a portal system.

This story is seperated accordingly into the crossovers, and can be read as such. It will start with the journey to the universe, and end with the journey from the universe back to Equestria. Only the prologue is an exception to his, and can be read if you have not read the prequel.

Any ideas for Crossovers/OC's/Universes are highly appreciated and will be considered.

(This is an alternate sequel to A Scientific Breakthrough, and what I intended it to be in the first place. This story will continue world-travel, and at the same time reduce the confusion previously caused by having a 'sequel within a story')
