En el año 2559/296 D.C., el UNSC inicia la colonización del recien descubierto sistema estelar "Omega Ascalon" en un intento por evacuar a supervivientes de los ataques de "Los Desterrados". Mientras tanto, en el continente occidental del planeta, sus habitantes pronto enfrentarán el cambio de reglas en el "Juegos de Tronos", cuando un lobo solitario vuelve al servicio activo.

After destroying the Flood and escaping the Ark Master Chief and Cortana find themselves on a strange new world where monsters roam freely, and magic truly exists. Together with Weiss Schnee, a huntress in training the unlikely trio will fight the forces of evil and save the world.

After suffering a Slipspace drive failure, the Crew of the UNSC Infinity alongside Battlegroup Dakota must find a way back to their own universe after being transported all the way to a similar Sol System but the Earth is declining and humanity is set on the brink of extinction.

The war against the Covenant ended, but something else pressed humanity to the verge of extinction like they never did. Now, Noble 6 rises again to defend humanity like he had done before, and make humanity into something strong like it was so long ago. The one thing his enemies keep wondering is why they hear boss music.

The mission's changed, they always do. Sam wasn't expecting entering another world with no possible way back, but his missions objectives remain the same, "Protect humanity, no matter the cost." At the same time, he will be forced to come to terms with his new home and learn what it means to be a hero in this new world. At least he doesn't have to do it alone. Sam and Big 3, C-2A

A chance encounter with Forerunner Technology leads the UNSC to discover a two-way portal which leads into a Universe so similar, yet ever so different from their own. First contact with said Universe's humanity, however, goes awfully wrong, sparking the greatest war since the Human-Covenant War. These are the tales of those who fought in it.

The Locust War on Sera was supposed to end. for good but a discovery of a mysterious alien artifact in Azura teleported Marcus and the Gears off to another universe, the world of Reach, The Gears found themselves drawn into something more significant than ever, another one had just begun. New allies, the Spartans. A new enemy and a new war to fight. A New Fight.

Spartans are instruments of war. They are molded, shaped, and bred to spill the blood of humanities countless enemies in the defense of mankind. They are not peacekeepers. They are not peacemakers. But duty alone will force a single Spartan to uphold a fragile peace or watch everything humanity could one day achieve burn. On the blood of their fathers and the blood of their sons.

"To dream is to be willing to sacrifice. To prevent those sacrifices from becoming too high is to fight. But you cannot fight and win by yourself. So I ask you: how much are you willing to sacrifice to make those dreams a reality?"

In forgotten ages past, two near eldritch forces vied for the very life essence of the Galaxy. Unknown to the young races, that war is still ongoing. how can the UNSC, the Citadel Council or the Covenant hope to stand against such forces, when they are still embroiled in their own petty squabbling? How could they hope to survive the War of the Old Ones?

The Spartans are trained to be unthinking, unflinching and unmoving in the face of the impossible. Project Atlas is so much more, when humanity looks up into the sky they can see Hope, Justice, Reverence. When those that seek to hurt humanity look up into the sky, they see the warrior, the monster, the demon. To those who seek the destruction of humanity, he is the Cataclysm.

Dying on Mantle's Approach, Cortana wakes up in an unfamiliar environment. In her drive to get home, she 'employs' the assistance of the local synthetics. She never wanted to be a galactic overlord. But a UNSC AI in an environment woefully unprepared for one of her caliber makes an easy one.

Spartan B311 was fighting alongside B312, Noble Six, as they made their last stand on Reach. Then with no explanation, B311 wakes up in the ruins of what was once a city on earth and that the year is 2287 instead of the year 2552.

You want and wish. People always say watch what you wish for. Will this wish lead to ruin, or turn out to be what he always dreamed? Sometimes you don't make a wish, and yet an invisible seemingly heartfelt one exists. Is this really what you want? You might not have said it but are you ready to face it?

After the final battle at the Ark, the Master Chief and his friends finds themselves on the obscure planet of Sera. There they've to team up with Sergeant Marcus Fenix and his Delta Squad to once again save humanity from enemies desiring its extermination, as well uncover hidden conspiracies that could determine the very fate of the universe.

Humanity and its allies have stood strong after the Great War with the Covenant. Follow the Systems Alliance as it goes through a first contact nearly as disastrous as the one that lead to the Great War.

What do you do when so much is thrown at you? What do you do when YOU wake up as an A.I.?

Spartans are the protectors of humanity. Headhunters are the sword of humanity. Both are required to fight for their species unto their dying breath. However, when death finally comes is that duty maintained? Does it continue as long as the mind can remember it? Regardless of the answer, a Headhunter must find a way to continue his duties. Even if he is no longer human. - Repost

Headhunter. Spartan. Killer. Cyrus was many things, but killer is the most accurate term. Now he stands in a city full of killers all vying to be top dog. Let those fools climb over one another to reach the apex. It won't matter because soon it will all come crashing down. All of it, for we are but motes of dust and echoes. From dust we rise and to dust we go. Semper Vigiles.

On the night Harry would have been dropped off by his Aunt, Dumbledore had someone else in mind. What if Harry was taken in by other strong people and they even decided to train him? Trained to be a Warrior by Wolves and the UNSC, he will change the world. OP, smart, trained Harry, small harem double cross with Witcher and Halo

a listen of story ideas i had thought about

Scattered, in a world where their emperor never existed... The Ultramarines have but one purpose... Protect humanity and act among them. Rated T for violence, death, and profanity. Please ignore the latest review. I have blocked that user for insulting words and feelings i do not support.

Death comes to all of us, Noble Six knew of It, so when he died he accepted It and was ready to join his fellow spartans. He did not expect to wake up on world way more fucked up than his. (Classified M due to gore)

A normal twenty-first century human mind stuck inside a Huragok, a Forerunner biobot, gets punted straight into the worst place anyone could ever be: Warhammer 40k. What is he to do but what he is made for? Beware all who call this horrid universe home, you will be 'halped'. First story on this site, updates every month. I have up to chapter 12 already written.
