Everything changes for Twilight Sparkle and her friends when a mysterious extraterrestrial ship crash lands in Equestria, its sole passenger a seemingly dead bipedal creature in hi-tech black armor. When Twilight messes around in the ship's systems with her magic, she ends up transported to an alien world unlike anything she imagined: a box canyon in the middle of nowhere.
Now, Twilight must enlist the help of the eccentric red and blue soldiers that live there... if she can get them to stop bickering with each other long enough to help her. Additionally, she finds herself being pursued by the enigmatic military faction known only as Project Freelancer. Back in Equestria, all is not well for Twilight's friends as forces involved with the crashed ship make themselves known. Reds, blues and ponies will all have to work together to discover the many mysteries surrounding the Princesses of Equestria and Project Freelancer.
A crossover with Red vs Blue. Don't be intimidated if you've never watched it, one of my goals with this is to make it accesible to anyone (though some references may pass over your head if you haven't).
I made a blog post explaining things. You should read it.
