Based on StarSerpent's Invicta Series It's been 13 years since the end of the Great War. The brewing cold war between the Human-Turian Alliance and the Citadel reaches a precipice. Enter Eden Prime, an insignificant colony made significant by the discovery of an intact Prothean Beacon. While the two great powers rush to cooperate, an ancient threat emerges from the shadows.

After the destruction of Requiem and an attack against Earth, both the UNSC and Covenant Separatist form the Systems Alliance. Then a discovery in the Deca-5 system changes everything for all sides. Cold War like conflict, lots of ONI , AU for Mass Effect and a council that actually thinks before it acts.

The UNSC has formed together with its former enemy's and found new allies, suddenly they discover a relay. Inspired by halo a new age and new dawn. First chapter is a timeline

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!)

Last time the UNSC discovered a mysterious alien artifact, the Halos came within seconds of activating. Every problem the UNSC has had in the last 50 years has been because of aliens and their blasted artifacts. So when a newly-surveyed system holds a mysterious artifact, there is great cause for worry. Operation RED COBRA is intended to remedy that worry- by any means necessary.

A codex for my AU Story, Mass Effect: First Contact, which has yet to be posted.

A changed humanity went into hibernation, having fallen prey to its own nature. Mountains formed, solar systems collapsed, and history went on without them. However, that story has not finished yet. A moral war that had once raged for tens of thousands of years will now be brought upon the Galactic Government's front door... for better or worse. (FIXED DISCONTINUITY IN CHAPTER 2)

They say when a miracle is needed most, it appears. But, what if the miracle that humanity needed most to survive the war didn't happened. What if they had a plan B? What if they had to leave known space to survive the covenant? Humanity lost the war A/U.

Humanity is still in the sol system but not for long and Jane Shepard's Grandparent's meet. War breaks out, the council gets ignored. Athena meets Arachnids from starship troopers. Does not follow cannon completely and is AU. It has Halo references and a few other genre's rated M for future chapter content. I DO NOT OWN MASS EFFECT/HALO/STARSHIP TROOPERS. MEANT FOR MATURE AUDIENCES

Space is infinite, but under the right conditions even a galaxy can feel too small.

As the war against the Covenant takes another turn, humanity must confront a wider galactic community beyond the known regions. (Currently being reworked and edited 20/03/2017) New version posted as Shadow Contingency (v2) - (10/06/2019)

One is ranked Hyper-Lethal, the other is the hero of the Citadel. One is a young SPARTAN-III, the other is a veteran N7 soldier. Both are soldiers and consider heroes, but only one is the perfect soldier. Who will win, the Lone Wolf or the Shepard. Rated M: For reasons.

"After the Great War the Unified Alliance is formed ushering a new golden age of both technology and Economy, But what happens when another first contact goes bad? How will humanity react to another possible Great War? And how will the Council react when all their Beliefs about technology are shattered?"

First part of a three part project: The Great war was finally over, with the Covenant and the Flood defeated there were no enemies left to fight, mankind could finally take a breath and enjoy the peace they had earned after twenty seven years of a war that had claimed twenty three billion lives. Or so they hoped. But the galaxy has never been that kind.

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?

Years after the Covenant Remnant founded by Jul M'dama had been destroyed, a new Covenant of Prophet-led Brutes attempt to attack humanity and its allies. One of the task forces sent to squash the upstarts triggers an unprecedented Slip-Space event. This is my very, VERY long-overdue answer to the Crossover Challenge by B1ue Ange1s. Rated T for now.

In a semi AU where Master Chief is Shepard's father and decides to visit her on the Normandy. Now complete. :D

The Galactic Encyclopedia, 2557 (Human) Edition, covers recent Human history, developments and the driving factors within the current state of Human affairs. Connected to the Invicta Series, namely Invicta: Second Front.

In 2525, the Covenant began its genocidal war against mankind. In 2541, 16 years after the start of the War, the Mars Archives are uncovered. The influx of new technologies, Human ingenuity and sheer ruthlessness helped turn the tide, turning a massacre into a bloody stalemate. It is now 2557, and the discovery of a Mass Relay leading to Unexplored Space will change everything. AU.

Three Heroes, different realities, different times. All of them are more than human. Mass Effect, Halo and Crysis crossover. M for swearing/cursing.

Humanity has joined forces with their former enemies to form the OSA, they have formed new alliances that have made them stronger, but what awaits them beyond the relay are they ready for a new chapter? inspired by Halo a new age and HaloMasssEffect: ruptured universe. this is a multicrossover (other franchises).

The galaxy is saved and the Citadel destroyed along with all synthetics. As Shepard is reawoken another time, he shall face the greatest evil of another universe...

SPARTAN-B312 has known conflict and pain his entire life. To overcome it, he became one of the best humanity had to offer. His entire existence had been inseparably tied to the sole purpose of duty. What happens when you take that from him, and everything he knows? Well, you are left an empty shell... and a very, very dangerous weapon.

A new mission. A new goal. New enemies, allies, technology, and a war not their own. As it has been said, if it were easy, it wouldn't be a Noble mission. This galaxy won't know what hit them.
