Extinction by Chris7221 reviews
Project Extinction was supposed to be the end of the Wraith, once and for all. All they had to do was fly back, activate it, and watch the fireworks. At least, that was the theory. In a strange new galaxy, with a terrifying threat looming over the horizon, finding a way back home may not be so easy.

Major and Commander by B0rnlucky reviews
Shepard gave everything she had to protect Humanity. She figured her fight was over and that she'd be able to finally sit down and have that drink with her boyfriend. Instead she finds herself face to face with a new threat in a new galaxy, and he only piece of sanity she has left is lost. If she ever hopes to find Garrus, she'll have to do what she does best: Save the Galaxy.

mass effect Atlantis by HENKLDORE reviews
the multi verse theory is proven to contain every possibility including a completely new universe Atlantis knows nothing about. Atlantis finds a new planet but the Stargate sends them to a new universe one without star gates or anything they will recognise. i had to downgrade and enhance certain technology but I'm keeping it as close to the technology of both sides as possible.

New, Old Friends by Flaming Back Lash reviews
The reapers are coming. They knew that but what they didn't know was that they had allies from before earth had space flight. This story is not going to be cannon.

Massive Bluff by Afalstein reviews
As it happens, not everything is what it seems in the world of Mass Effect. The Prothean Beacon isn't quite what Shepard made it out to be, the Reapers aren't really the Reapers, and the Collectors DEFINITELY aren't the Collectors. John Shepard is still John Shepard, but not the one everyone thinks he is. Rating for some innuendo. AU.

Should we even pretend? by Forohe Toxophilus reviews
Atlantis has been taken by Replicators, and Rodney McKay's virus is the only way to get past the shield- except that it sent them to an entirely different, parallel, universe. THIS IS A TEST FLAG. I'm trying out the waters of this type of fic. Never attempted a crossover, so this will be interesting. More information inside.
