My Effect: Crossover by
Lanilen reviews
If the laws of the Universe can be broken to make some of us, players, end up in the Mass Effect universe, what else could they do? A silly one-shot with me meeting myself from different Self-insert timelines during the raid of Eden Prime.

Transcendent Humanity by
Solaris242 reviews
Humanity never developed FTL. The Prothean archives contained no technology, no Element Zero, just a warning. Isolated from the rest of the galaxy for two thousand years, restricted to their only system, how will humanity have changed when they first meet the Turians? AU, alternate history of humanity and First Contact.

Mass Impact by
Quietness731 reviews
This was the Mass effect universe, there was no other feasible explanation other then that someone had drugged me, or that I was dreaming. I almost never dreamed and I was never addicted to any kind of drugs, plus the fact that no one would've checked in on me after I was unconscious since I never had many close friends after I had fled my home country. I had to stop the Reapers.

Mass Effect: The Odd Ones Out by
GIRLIKESTACOS reviews
None of us ever thought we would see the splendor of the Mass Effect universe outside of the games. The cool locations, people, technology, we knew it was impossible. Those thoughts were shattered in an instant when me and a few of my ragtag friends mysteriously ended up in the world of Mass Effect, joining up with Commander Shepard herself. Things would certainly be interesting.

Hero, I am Not by
Soleneus reviews
The first time I ever tried to be a hero, I got shot in the head. The next time I woke, the first thought that crossed my mind, after 'Why am I waking up' was 'Why are those women blue' A self-insert that's different from my usual fare. Pairings are a toss-up.

The UNSC and the Imperium have agreed on hosting an exchange between two Spartans and two Space Marines. What kind of hijinks will ensue? Inspired by the story "Marcius Flavius" on 1d4chan, which means it's going to be slight crack. Rated T for now. Might change to M because of violence.
