Saddle Arabia had always been known for its unusual rate of crime, but recently they have shut themselves off from the rest of the world. Investigations soon discover that a Communist government has taken over, enslaving citizens and brutally harming anypony who resists their power. The newly-formed Communist territory is now turning their sights to conquer the rest of Equestria.

The EMC (Equestria Marine Corps) are sent in with haste to quickly quench the tyrants' power, before the Domino Effect soon falls into play. The main goals: rescue captured Marines that were stationed in Saddle Arabia, and destroy any and all enemy contacts.

But war always has a cost.
