Battle of Ponyville (Great P365 War)

"The Battle of Ponyville is gonna be like Stalingrad all over again since the Allied Forces of Harmonic Friendship knew they're losing the war despite their best efforts... until recently, Twilight Sparkle returned to the surface. I knew Ponyville and Canterlot are both the last remaining cities of Equestria that are yet to be conquered while Manehattan is the recent addition for the New Group P365... and even to these meanies for the Manehattan Cake. Well, we gotta defend Ponyville before it's too late."

--Su Ji-Hoon, Equestria Never Surrenders

The Battle of Ponyville is the massive battle between the Allied Forces of Harmonia versus the undead hordes of the New Group P365 that it would be happened in during the Great P365 War.

When Ponyville and Canterlot are the last Equestrian holdouts during the Great P365 War before Twilight's arrival since the Manehattan Cake was ongoing in post-Last Day

The allied soldiers must defend Ponyville when Equestria need the assistance of the allied soldiers from each nations of Harmonia.
