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.

A HALO/Mass Effect cross over I came up with a few years ago and uploaded on my old account so just in case you guys think this is a stolen work please note: I am remaking it without my more... rubbish earlier works clogging my list.

Story won't be updated anymore. Grammar and spelling is bad, be warned.

In 2157, Humanity was busy opening Relays, trying to explore the Galaxy. At the same time, in a nearby galaxy, the UNSC may be about to engage in the second Human-Covenant war. Will the UNSC and the Alliance be able to help each other, or will both fall to the reapers and Covenant?

In 2560, just years after the end of hostilities between the Earth based UNSC and the New Colonial Alliance, the Industrial colony of Falkland is slowly being turned into a Fortress as a defense against the perceived Colonial threat. But within months of his transfer to the colony, Lance Corporal David Campbell will find out first hand whether or not the fortress will hold.

Multiple crossovers AvP,RvB, JC's Avatar, Star wars, Halo, Mass Effect and more. Authors 2nd apology and Cancellation on chapter 14

This story is about Noble Six in Shepard's crew during Mass Effect 2. This is my first fic, please be nice.

I decided to move the timeline and technology database into their own section, so readers who just want the story can have that now.

Space was not as the idealists thought, no prosperity or enlightenment. Humanity has been at war, with itself and with alien races, since it first left the Sol System. The Innies, the Zealots and the turians failed to beat the UNSC and Shepard will be damned if he's gonna let some ship with a god complex succeed. Not on his watch.

It's all a matter of perspective...

During a routine patrol, a Turian flottila encounters a new race activating Relay 314. The ensuing events will change humanity, council space and the individuals involved.

While the Infinty preps for a joint mission with Covenant allies, an ancient plan is set into motion to herald in a new age of war. NB: This series will include more than just the indicated xovers. There will be more leading into a final story.

Mars Base is a military base on mars. This book follows the character of Garrus, a team leader who goes through a lot.
