Cancelled

Future "me" gets teleported into the Mass Effect universe, along with good'ol Chief and Cortana. Sort of a semi self-insert and crossover fic. I probably won't update often, so don't expect too much.

During the battle for Earth, a few UNSC soldiers make contact with a group of aliens, with their new allies they try to do all they can to save their species. Meanwhile, one of the remaining inner colonies, Shanxi, goes dark.

Some of the most influencial individuals in the galaxy are putting together a team, the team just isn't too clear as to why just yet. Halo/Mass Effect/Portal cross. T for bad language and violence. Slight M/M romance subplot, nothing major though.

The SR-2 discovers a abandoned ship. The Ship's name: Forward Unto Dawn.

The Flood, the Precursors, the Forerunners, the Reapers, and the Protheans. Seemingly unconnected, they are all intertwined in some way. Want to know how? Read on!

A UNSC Powler ends up in Counsle space... along with it's smart AI Nicknamed "Josh" Judging by the citidal's attitude towards AI's this should be intresting. All of the prowlers crew are OC. Told from Josh's POV. Chapter 4 now up!

Six didnt die at reach. She was saved by the Spartan Squad HADES. And together, they escape reach...by going to a new universe. Fem-Six/OC, Fem-Shepard/OC, Rated T, may go up to M.

Shepard, Six, and co attempt to pick up a legendary soldier from the Forward Unto Dawn. They arrive too late, a frozen Master Chief being the hottest commodity in the galaxy. When the Collectors appear things change, a new enemy rises for all to face.

The unthinkable has occurred. Two universes are about to collide and can be pretty confusing for the ones involved. What happens when a group of supersoldiers, trained solely on fighting aliens, finds themselves in the world of Mass Effect?

Two years after the demise of the human Reaper, Shepard makes contact with a new species and the war climbs to a new level. Her only chances of survival lie in becoming a SPARTAN. F/F, F/M. AU -Temporary Hiatus due to rewrite

Ideas and suggestions for any writer out there who has or wants the proper inspiration to crossover Halo and MassEffect! Merging them can be difficult, and most fics on this site... suck a little, except for a few I recommend inside.

Humanity...such an odd name for a species that saved us...They opened the way for our survival at the cost of their own lives and everything in our world changed forever. A Halo/Battlezone1998/Mass Effect crossover. Heavily AU. You have been warned.

After the fall of Reach, Noble 6 like a ghost finds himself in another reality, waging another battle for a different cause. Shepard and co attempt to thwart the Reapers with his help. Sovereign has other plans...

Noble six with a lady of your choosing from the mass effect universe, I'll make it work.

Scrapped, rewrite being planned

With the UNSC-Covenant war over the ruined remains of the UNSC face war with an unknown enemy. Their best hope in adverting a war is sending an advanced stealth warship, the first and only of its kind. The Incursion has begun.

The rest of the galaxy may know John Shepard as the first human spectre, but there was a reason why he was chosen above everyone else for this honor. These are the early years of ODST John before he was John Shepard the first human spectre

A crossover, Spirit of Fire and John Sheppard from mass effect. The spirit has escaped the shield world, but now they have no idea where they are, or where to go, until they come into contact with other humans who have never heard of the covenant or UNSC
