Equestria.
The shining pinnacle of everything good about the world of Equis.

The Badlands.
The run-down hole of everything terrible about the world of Earth.

When a massive corporation fires one of its Snipers for failing to perform well enough in the field, he ends up transported from Earth to Equis. Hoping to make some new friends, he sets about socializing. However, this is harder than it seems, especially when he's not the only one to be taken there. After all, how is a murdering gunman with low self-esteem going to fit in when placed in a country full of peaceful equines with friendly attitudes and whilst under fire from everything that isn't himself?

Horribly, I assume.
