Halo: Feet First covers the story of a team of UNSC Orbital Drop Shock Troopers of the 7th Battalion, 105th Shock Troops Division. The main character, Duncan Iris, faces the full horror of the covenant war effort against humanity as well as the brave retaliation of outnumbered and outgunned UNSC forces. However, he also witnesses the turning of the tides as the war progresses.

All of them united would be an unstoppable force. would be a lot more to come and go as now. Rated T for violence, death, and profanity.

Come gather around me and listen while I speak of the legend of Ship Master Ada 'Brasov.

Or 'How I became the bane of Humanity's enemies'. It just happened. I was there. It was ugly as hell, but now I'm helping as much as I can. Of course, things had to start in Harvest... but I'm not alone. (Halo Marine!Insert) (Some characters have been Genderbent, just a few)

She was a hero from a time long past. He was slaughtering her people by the billions. What is a hero displaced 500 years into the future to do? Note: Soul bond; please be nice when telling me this is bad. Also, mentions of My Hero Academia and some Marvel references are made, but that's it.

Fireteam Storm is deployed to Infinity as a security escort to Dr. Halsey, while Infinity is engaged in the 2nd Requiem Campaign. Authors Note: This is my first attempt at writing a non-action related story. This story is told from Spartan Frank Jackson's perspective, and takes place during Halo 4 Spartan Ops.

Orphaned by the Covenant, Presly and his Sister Galli are taken in by an Insurrectionist Cell. The attack on their home unlocked something in them. Something from the distant past but still brimming with anger and hatred while yearning for a chance to right certain wrongs.

CIVILIAN SOS BEACON DETECTED. UNSC CORVETTE PRIMO VICTORIA DISPATCHED. ASSIGNED MISSION LEAD: SPARTAN COBB. SITUATION DEVELOPING.

Their bond was unique among spartans… Even as it slowly ripped them apart. Rated T for violence, death, and profanity. Does NOT follow series and such. Updates infrequent currently.

With ARC DREAM on the line and no hope of reinforcements, Maddie stands alone against the odds and fights for the future of all mankind. On Ballast, a legend is born. (Spook 3/5)

ODST Private First Class Korbin Montgomery has had it with Zeta Halo. First, the UNSC loses to the Banished- effectively scattering the UNSC's forces all over the surface of the ring- then she lands on a dead Spartan-ll. What the hell else can possibly go wrong? Basically just a romance between Master Chief and an ODST OC.

It has been 15 years since the Battle on the ark. Now awoken, John finds himself in a galaxy at war. Human and Alien factions fight for control in a power vacuum left by the destruction of the Covenant and UNSC. With is former loyalties gone, the galaxy at war, the Chief now needs to decide if he's human or machine. Harems and sex.

New story based on one of the best videogames ever. Co-op by me and TME. OC's will be used to make the plot more twisted. Expect cannon and references being used in the story. Constructive criticism is welcome. no flames please.
