After discovering an ancient artifact, the UNSC's most advanced warship and a Sangheili Assault Carrier are transported to a universe unlike anything they have ever seen, and forced into a war against a foe they never could have imagined.

A young Death Korp soldier, in a battle with a follower of Chaos, ends up swallowed by the Warp. By a stroke of luck, he's sent to Earth, to a world without an Emperor, to a world where villains and heroes battle it out across the globe. With no Emperor to serve and no war to fight, this young soldier must struggle to find his own path in a world that challenges all his beliefs.

Morality and mercy are easy concepts to follow when there are no risks involved. But it will always come a day where it's not easy, when a person must choose; to die honorably like a hero, or to do the unthinkable and survive. So tell me this. Stranded and all alone in a cruel land inhabited by men that despise mercy and compassion, what will you choose, Raven? To die? Or to live?

From Halo's ashes, a mismatched Alliance is born. UNSC soldiers now serve alongside both Batarian deserters and shifty Jackal Space Pirates. Now Shepard and Master Chief have to keep these strange bedfellows from killing one another before they can stop an emergent new threat to the galaxy. The Next Swashbuckling Chapter of the Wormhole Chronicles.

Everyone's favorite Spartan is looking for a new purpose, lucky for him, the Commander his happy to oblige. (5-23-19 Info: On Hiatus after Chapter 45. Will update with schedule after life is in order.)

Liara T'Soni continued her mission to protect the Galaxy while Commander Shepard is in another dimension. She must stop the Covenant and the allies they've gathered from wreaking havoc in a Galaxy without it's greatest hero. While she's had some success, there's a gathering storm on the horizon and one of her crew of misfits will be forced to confront her past before it clears.

Continuing from Best of Spartans and Spectres. Commander Shepard has been captured and Noble Six turns to the one group that can help save her, but will that help come at too great of a cost?

Spartans never die, they say. When Jorge gave his life to save his home planet of Reach, he never imagined that he would survive. But now he finds himself neck deep in the troubles of another universe; he will do what he has been trained to do, what all Spartans do best: fight.

An AU fic in which the Halo and ME universes share the same galaxy. After a well deserved rest in Cryo-Sleep, Master Chief finally awakens...to a whole new galaxy.

Sangheili Arbiter Thel 'Vadam has fought the Flood and The Prophet of Truth. Commander Jane Shepard has fought the Reapers and the Collectors. Both are leaders, warriors, and survivors, but while the Arbiter knows the price of galactic genocide, Shepard does not yet understand it, nor does she understand it as the Arbiter understands it. But she will be forced to understand.

The death of a minor demon tears a hole in warp space, sending the Master Chief, a Dominion Ghost, an Inquisitor of the Imperium of man and their companions into the Reaper-verse. On the bright side, Shepard gains some powerful allies. Contains some language, decent amounts of violence, and several OCs.

After the the Crucible is fired, the dark energy from the blast sends Commander Shepard someplace . . . different. Now her best (and only) chance to get home is a suicidal quest to destroy one ring. Fortunately Abigail Shepard is a rather old hat with suicide missions. Female Shepard, Vanguard, War Hero, Paragade. Post ME3 ending. Contains explicit language, heavy violence.

Warpstone is a fickle thing. After the destruction of the Skittergate, a pulse of pure chaotic energy sends the entirety of Helmgart into another world. Now the Ubersreik Five and their assistance at Taal's Horn Keep find themselves within a new yet familiar world. A world where the moon Morrslieb and Mannsleib can be seen in the same night. Warning: This is graphic. Seriously.

Emile survives the two zealots at the end of Reach, and after surviving Covenant onslaught, finds himself in the ME universe. Kick-ass picture is thanks to freejimmy on deviantart

After a struggle to save an Imperial world from damnation, the remains of an Inquisitorial team and their temporary Eldar Allies are thrown into a universe the antithesis of their own.

Remembered by history they thought his body belonged to Reach. To his purpose he rose again not only to defend humanity but a galaxy full of those who cried for freedom. Together, he bleed with them but he still failed. Can he shed his apprehension and work alongside the one human and her team who can stop the terror from beyond the darkness? This is the next chapter of Six's tale.

The Cycle marches ever onward. 100,000 years ago a race virtually unknown to Citadel space established an Empire that spanned the galaxy. Two Cycles later, their ruins gave rise to a Covenant bound in their worship. These aliens evolved outside of the Reapers' plan, and now threaten to upset it as their gods had eons before. (Rewrite in progress!)

Everything...taken from me. Gone from the world I once knew and thrown into an universe I couldn't imagine. Stuck within a world of creatures beyond my imagining, of hunters and huntresses. I have to get out of here, finally recovered I can start over. I have to go, I have to find the way back. (DISCONTINUED, but reboot is here)

In 2157 a Citadel Council exploratory vessel is tasked with opening a dormant Relay into unknown regions of the galaxy. What they find is something they never expected. What happens when two civilizations centered around different technologies clash?

DISCONTINUED. A joke of Chaos daemon sent two unlikely allies - an Eldar Farseer and an Imperial Storm trooper, through the Warp and into another Universe. In this place, everything is alien to them. Except for one thing - war. War is something they know very well.

"No army is big enough to conquer the galaxy. But faith alone can overturn the universe", Missionaries are skilled in oration, manipulation, and subtly changing a culture to bring it into line with the Imperial Cult, replacing the gods of the existing pantheon with Imperial Saints, they are also often skilled warriors not above the use of brute force.

None are more devout or more fanatical than the Sororitas and none more than the Sisters of Battle among their ranks. They scour all before them that would mar human perfection, purging the xeno, heretic, and mutant with no pity with remorse. Nothing of alien origin lives where they tread, but how does one sister's faith fare when she is confronted with a world that is so wrong?

But Halo holds a secret, one deadlier than both the Covenant and Reapers combined... and it's hungry.

The universe is a big place. Thousands of light-years still awaiting exploration, keeping secrets unknown to the rest of Council space. The Reapers were proof of that, as much as the Council is loathe to admit it. But there are yet secrets that even the Reapers, or their masters, the Leviathans know about. Even the apex races can be surprised. UNDER HIATUS

Noble Six laid in a puddle of his own blood, slowly but surely approaching death's door. Six raised his right arm towards the sky, in a last ditch attempt at a type of prayer to whatever God that was out there, Noble Six wanted to live.

The Reapers have been harvesting the organic races of the galaxy since time immemorial, but the galaxy is a big place; even they cannot cover everything. Within the myriad cracks they left, the Forerunners and humanity arose. What will happen when the UNSC encounters the numerous other races of the galaxy, just in time to witness the Reapers' return? AU. Post-H4/pre-ME1.

Rookie drops into a whole new universe. But this time, he's not alone. He'll find new enemies and new allies, a whole universe and all of it's intricacies. Luckily he's got the firepower to deal with it all.

The Great Wars are over. Jim Raynor and his men have left the Koprulu Sector behind, choosing to settle a world away from that sector of space. Unfortunately, the colony of Shanxi is not safe; hostile aliens have invaded, intent on controlling the Terrans and their bizarre technology. Unfortunately for the Turians, the Terrans have experience fighting hostile alien invaders.

When adversity bares its abyssal maw, when an unstoppable, terrifying enemy erupts from a literal hell to consume all, you must take the proffered hand and lean upon whatever is left. Even if previously you were engaged in a galactic slaughter with your enemy turned ally. In dire times such as these, they must rise above the cataclysm... Were it so easy...

As Humanity continues to survive its own desolation, a probe from its past is found by a lone Quarian scout ship looking for new resources for the Migrant Fleet. They followed it back home, and found only ruins. They didn't expect to find survivors.

John had always known what he could do, if given a challenge. He'd known his capabilities ever since he'd been a child, let alone a SPARTAN. But now, after surviving a trip he honestly shouldn't have, he's stuck on a planet with no orders, no manual, and no amount of training that could've prepared him for the situation he's now faced with... a Mindoir farm girl named Shepard.

200 years have passed since Millennium's attack on London. Mankind's technology has advanced amazingly with the discovery of alien ruins on Mars, and the whole galaxy has opened up. Seras has seen it as her duty to protect humanity ever since Hellsing died, and joining the Alliance Military seemed the perfect route. Now the galaxy will face something new, a Vampire Spectre.

You all liked my Codex so I decided to do a story! So for you new people here's the premise: UNSC super militaristic after the war and built up an empire to match it, HSA being founded by the insurrectionists back in the 2540's an 171 years later once again meeting there old FORGOTTEN foe, and the 12 colonies and Citadel trapped between both.

Yang Xiao Long finds herself in Lordran, and with a lot of questions she isn't getting answers to.

Imagine a Halo/ME Xover where humanity didn't: become BFF's with the elites, stomp the turians at Shanxi, become besties with the quarians, defend the krogan and true geth against the EVIL council and then kick said council to the curb. Imagine it didn't become just a retread of the first game. Imagine it didn't start with a timeline. This is my attempt at that.

What would the Mass Effect/Halo/and BSG galaxy be like if they were all fused? If the Systems Alliance was the descendants of insurrectionists if the UNSC goes super militaristic, if the poor Colonials are trapped between technologically advanced nations. This is a codex of the three humanities and how you respond to it depends if I go and make the real story

In a twist of fate, the Covenant never encounter the humans on Harvest due to a slipspace malfunction and end up near the Turian colony of Taetrus. Declaring the Turians, as well as the rest of the Citadel races as Heretics, the Covenant invade Citadel space on a campaign of genocide as the Council breaks its most sacred laws and traditions for one single goal: survival.

An ancient threat awakens. A strange ship crashes into a frontier world. A chance encounter, that will change the fate of the entire galaxy. The battle for the future begins, at the end of all things... Infinity's Gate!

*HIATUS* Reboot of: A Spartan Alone - Jastis-015, a Spartan-II, falls into another dimension, one where his squad doesn't exist and neither does the UNSC. Alone on a strange world with new races and a familiar one, the Spartan must now survive and try to get back home. Pre-Halo 4, Post-ME3. Mostly OC cast. *HIATUS*

The road to hell is paved with good intentions. Commander Shepard stopped at nothing to fight the Reapers. But with the Reapers now gone, what new threats might emerge in their absence? FemShep & Liara pairing.

The Farsight Enclaves led by General Farsight have broken free of the Ethereals and have survived both the Orks and Tyranids. But with the development of a warp storm which rapidly consumed the their planets and left them in another galaxy altogether. One without the endless bloodshed.They thought that they were now truly free to build their future. But life is never that easy.

Mass Effect is a great game. A fun game. But the fun and games stop when it all becomes real...when I find myself on the Citadel, with the terrible knowledge of what's coming. Can one person really make a difference? I'm sure as hell going to try, because the Reapers aren't taking over this galaxy on my watch.

The remaining Forerunners leave their home galaxy for a new, only to find somethings will never leave them.

A Halo/Mass Effect crossover, though not a typical one. This is the story of the last Forerunner, sent to a different galaxy entirely. How will he handle himself in this new glaxy where everything is different. Adopted from drich147. I corrected a mistake in chapter 3 regarding how long he has been there. I do not own Mass Effect or Halo.

When a Great Journey ends, another begins...As the Normandy is assigned to pick up an artefact located on Eden Prime an Alliance scouting flotilla discovers something which could forever change their destined path; They thought that the Citadel was an engineering marvel...they hadn't seen Capital.

It has hardly been a month since the defeat of Harbinger and its Reapers when a massive fleet seemingly appears from out of nowhere. Once again Earth is the sight of a cataclysmic war between the alliance of humans and aliens and this new foe led by a man who calls himself 'The Despoiler."

Knowing that the flood cannot be contained in the milky way galaxy for long. A lifeworker and her team are sent to a neighbouring galaxy to prepare the local species for war against the parasite. And to index them in case the parasite wins.

Humanity has expanded throughout the galaxy with the use of slip-space and the mass-relay network. They have endured the tests of a space-faring society but something lurks in the dark. The Covenant have dominated more races and have discovered Humanity, declaring their genocidal campaign. Is there any hope that Humanity will survive? Not your normal crossover. Multiple view points

Shepherd is on Eden Prime, minding her own business when a Husk gets sniped with a gun shooting odd pink crystals. In orbit, Anderson sees an unknown dreadnaught blow apart a small Geth fleet. But wait, it's a frigate? What's a Freelancer, and where in the heck is Blood Gulch?

An asari exploration vessel discovers Earth in the 2030's...and the first contact scenario has incredible implications for both species. What does humanity look like through alien eyes? Where do they go from here? /-AU: no Reapers, completely disconnected from the plot of the games, but mostly faithful to the setting. Told from many points of view.

With the Fall of Reach nearly complete, the Covenant sends it full might to eliminate one Spartan. With a little of John-117's luck rubbing off to another hyper-leathal soldier, she finds a new fate awaiting her beyond Reach.

Zer0 seeks out a challenge, something that was difficult, something he could view as an equal. After a series of lackluster contracts, the lure of a vault and the rumors of the danger surrounding it is enough to take the assassin down a path that might prove to be the very thing he is searching for. Zer0 will be the main focus, but multiple POVs from all the vault hunters as well.

One minute, I'm at home; the next, I'm in a wretched hive of alien criminals. This universe is a death-trap; the apocalypse is coming and the Reapers are going to kill us all. I'm no soldier, I'm a cowardly thinker. To survive, I'll have to think outside the box. But first, I have to survive Omega. To do that, I'll have to cast my lot in with the ruler of this rock, Aria T'Loak.

RedvsBlue Crossover- This is the worst summary... ever... of all time

"I came, I saw, I conquered." Julius Ceasar. In the 21st century humans make rapid advances into space, with individual nations striving to create their own interstellar empires. Space, for most people, was a means to escape, to leave a conflicted, divided and violent world. But wherever man went, devastation soon followed. (Title Changed)
