Group P365's Tombstone Research Incident

"The Group P365 had started a horrible incident that woyld help their former human Gerasecian soldiers find the tombstones of the deceased in Canterlot City so they can be turned into zombies. It seems that this nightmare in all over this different-looking, human-dominated city in this alternate world is about to get much, much worse."

--Su Ji-Hoon, The Tombstones

The Group P365's Tombstone Research Incident is a incident events that most of Group P365's former human Gerasecian soldiers who find tombstones were deceased and turned into zombies.

It would be happened when the Group P365's former human Gerasecian soldiers want to find and research the tombstones from outside of Canterlot City that they would be killed by neutral civilian zombies who came from tombstones .And later caused the Group P365's former human Gerasecian soldiers resist,which now overwhelmed and failed.

Therefore, maybe their squads were killed and turned into one of zombie soldiers by their zombie traitors or neutral civilian zombies. When most of Group P365's former human Gerasecian soldiers are zombie soldiers,they will attack the Canterlot High School after entered Canterlot City, similar as the German zombies from COD Zombie map Origins
