[All characters are humanized]

Have you ever woken up somewhere you didn't recognized or even know how you got there in the first place?
Would you even believe me if I told you that I'm in a world which is based on a TV show about colorful ponies with magic and or wings, but instead they are human beings based on those same characters from that same show?
I thought that my knowledge of this place would help me out here and maybe help me get back home.
But I was wrong.

"Sleep is like the drug of our generation--we claim we don't need it, but we always find ourselves entangled in it's hopeless temptation."

When seven ponies wake up in a large mansion, unknowing of their situations and the others themselves, they find that they are involuntarily thrown into a game of endurance, and survival. The rules are simple: Do not fall asleep.

The last one awake gets to walk away, free.

The other six will never wake up.

Just how "overrated" is sleep, anyways?

This story is a sequel to Stardust

Times are changing for Equestria as Twilight’s return brings with it news of people and cultures from beyond the peaceful world everypony knows. Aid and volunteers are freely offered to help the besieged humans of Earth because every Equestrian knows that’s what good friends do. Unfortunately, making friends can also have the unintended consequence of making enemies.

When the monsters besieging the humans strike at Equestria with a level of brutality not seen in over a thousand years, the cry for help is sent to all the kingdoms of the world. Honored allies step forth to fulfill ancient treaties and oaths. Enemies, old and new, bury their grievances. An alliance never before seen in Equestria will be created to combat the monsters from the void.

And because of these events, a grim but welcome sibling to the XCOM project is born.

(XCOM/FiM Crossover)
(Sequel to Stardust, which I recommend reading before starting this. Fortitude Amicitia and Broken aren't required reading but are supplemental to the storyline)
(Gore tag for blood and violence)
(Alternate Universe tag because of the divergence from canon that Stardust has caused)
(Uses elements of Season 4)
(Coverart produced by the amazing Carnelian!)
(Many thanks to Arzoo, BradTheBrony, Vandenbz and Setokaiva for prereading!)
(As of 03/07/2016, the prereading team consists of Arzoo, BradTheBrony, Noble Cause and Metallusionsismagic!)
(Complete with it's own TVTropes page as part of the Stardust continuity. Could use some updating!)
(Character tags will be added as chapters are added!)

(Possible spoilers in the comments! BEWARE!)

The land of Equestria... What once was a sprawling empire of peace and tranquility is now a corrupt diarchy with a dissatisfied populace. Several movements have arisen to take the challenge of turning the country around and one such movement is the Equestrian Communist Party lead by the great bolshevik pony Iron Curtain. Rallying around the farmers, and factory workers of Equestria, Iron and his close friends Steelhoof and Trotsky are determined to bring the Equestrian government to its knees. This is the story of a struggle for power. This is the story of the rise of Soviet Equestria...

Twilight Sparkle is replaced by a firetruck.

I'm never writing another story.

Seriously, this is it.
