Exposition for those who don't follow Mass Effect. Spoilers for Mass Effect 3, because obviously.

The N7 Marine Corps are some of the most hardcore fighters in the galaxy - regardless of whether or not they actually are N7s. And if you need a job done and Commander Shepard's off saving the galaxy, Omega Squad is the team you ask for. This unexpectedly popular collection of species and classes biotically rends every Cerberus shock troop they find into pieces, zaps rogue Geth into unresponsive electrified hulks, shoots Husks in the face, and beat Collectors into shreds with superior firepower.

And then the obvious happens. During the Battle of Earth, the Crucible fires, and... something happens. Nobody quite knows what, but in the end, Omega Squad gets teleported to a very, very familiar place to you all... Equestria.

So what happens when you teleport six trigger-happy, tired N7s into a land of peace and friendship? This happens.

Join Urdnot Barx, the Krogan Soldier, Yelena Secari, the Asari Adept, Dari'Nara vas Tonbay, the Quarian Engineer, "Hitman", the Geth Infiltrator, Samuel Harrison, the Human Vanguard, and Martilus Hinfax, the Only Sane Turian (and Sentinel) as they adjust to life in a place that at best is a major cultural shock and at worst not fit for their type of life. The N7s are favored for their ability to adapt to any type of environment... which begs the question; can they adapt to this? (Spoilers: They can.)
