2022 REWRITE IN PROGRESS

After being rudely awoken from Cryo-sleep, John-117 finds that the Forward Unto Dawn has been sucked into a gravity well, causing it to fall towards an unknown planet. In the crash, he is separated from Cortana and falls alone into the Everfree forest. In addition to this new complication, old memories from a scarred and tragic past haunt his dreams, putting his remaining sanity on edge.

However, he has little time to ponder these thoughts, as he encounters the planet's... peculiar... inhabitants.

First 19 Chapters proofread by Bravo 539 and Shadownamesto.
Credit for the intro sequence goes to Blaze Spectrum.

Current rewrite will not necessarily follow the old story but certain events and details may be reused.

The equestrians have forgotten us, forgotten of those they once fought side by side with, lived and coexisted with. Those who they had once called brothers and sisters. I am here to remedy that, to bring back the forgotten histories of Equestria.

Part one: First contact

EDIT: The story has undergone a rewrite and I added a few new elements to the existing chapters. You may want to reread them ^^

Metal Gear has fallen into the hooves of an Equestrian revolutionary, who, with the backing of his human mercenary allies, intends to use it to depose Celestia and crown himself ruler. Having crossed into Equestria in pursuit of this rogue weapon, the legendary Solid Snake must ally with the residents of Ponyville to prevent a nuclear catastrophe.

See also Equestria Gear Solid, the hilarious spin-off EQG parody in which everything you know is wrong, and every single character from the story is an awful caricature of themselves.

Now with its own TVtropes page!

It is the year 2552 and the Pillar Of Autumn has just entered Slip space to escape the Covenant fleet at Reach. A malfunction occurs with the Slip space drive and sends the Autumn and her crew into unknown space. The first planet that comes into range is very Earth like, and is giving off intelligent life signatures. What they don't know is that their only way back home is on this planet. The Autumn dispatches a scout party and what they report back is unbelievable. A world completely inhabited by ponies, millions of them..... Welcome to Halo: Equestria.

I'll add in more character tags as they are introduced in the story.

In the grim darkness of the far future, there are only ponies! Equestria is assailed by countless foes from without, but only the shadowy Friendquisition can protect it from the enemies within. Can one Inquisipony and his team uncover a plot that threatens to destroy everything they hold dear? Or will sinister forces prevail in an MLP future that has become like the Warhammer 40k universe, the original grimdark franchise?

As seen at Equestria Daily. Note that the most recent version of the story, including edits and new chapters, will be available there first, and changes will eventually trickle over here. Please feel encouraged to leave comments here, there or at this thread on Ponychan. I would very much like to hear from you.

The Princess Protects

We should have acted. He’s already here. It was foretold that He would return. His defeat was merely a delay… ‘til the time after Nightmare Moon’s return, after Discord spread chaos across the world. But nopony wanted to believe… believe it could be true. And when the truth finally dawns, it dawns in fire!
But, there is one He fears. In His tongue, he is Dovahkiin… Dragonborn!
