The Random Chimp Event

== "People of America, today we begin our struggle for survival." ==
During the summer of 2021, monkeys of all kinds (contrary to the name of the crisis) rose up against humanity. They cause wanton destruction and murdered millions, rapidly overwhelming local and provincial police 
forces worldwide, leading to world leaders dispatching their militaries to the streets. After three weeks of constant fighting, the monkeys left alive fled back into the wild, employing scorched earth retreat tactics to cause further destruction as humanity attempted to restore order. The event revealed that all species of primate, besides humanity, were vastly more numerous in population than previously understood. The chimpanzee population had been believed to be around 300,000, though over 20,000,000 chimpanzees alone were killed over the three weeks of war.
=== As it happened ===
On the 3rd of July, 2021, the first wave of gorillas was sighted leaving the Amazon Rainforest and travelling North towards Mexico. It rapidly became clear that there was purpose to their march. The gorillas demonstrated extreme violence on their march, killing thousands of humans and slaughtering livestock as they moved. Shortly afterwards, primates began to emerge from forests and jungles all over the world, leading to NATO conferring with The Huntsman's Guild and Aperture Security on the emerging incident. On the recommendation of these parties, they instated martial law across the Western World, declaring a state of emergency and temporarily cancelling restrictions on previously banned weaponry - Chimpcon One had been declared.
After three weeks of intense fighting in every corner of the world, much of which was poorly recorded due to the utter chaos, Chimpcon One was finally lifted as the primates retreated. NATO, the US Senate, The Huntsman's Guild, the mages of Big Sky and worldwide governments and chimp experts banded together to begin recovery operations. Aperture Security was officially instated by NATO as the worldwide authority on chimp culture and combat, granting them a massive injection of funds to open shelters, arms stations and agents worldwide.
=== Notable Cities Lost to the chimps ===
* Zagreb - permanently destroyed due to carpet bombing by Croatian government after the military was overrun.
* Detroit - largely abandoned due to extensive damage to property and infrastructure.
* San Francisco - cut off when the Golden Gate Bridge was destroyed by the US military.
* Edinburgh - destroyed due to extensive deployment of ground vehicles by the British Army.
* Toronto - destroyed by nuclear detonation after the sighting of a gorilla army rising from below ground.
* Novohrad-Volyns'kyi - evacuated and promptly destroyed by firebombs by the Ukrainian military.
* Athens - damaged beyond repair and largely abandoned by excessive use of ground vehicles and airstrikes by the Greek army.
=== Casualties ===
Approximately 17,500,000 humans were killed worldwide, in addition to 35,000,000 monkeys. 
===== The Aftermath =====
Hundreds of billions of dollars were sent as aid packages by the US government to assist other countries. Over the next six months, most of the world was able to return to something close to 'normal,' their cities rebuilt and their loved ones mourned. Many countries took to arm their police forces and deploy permanent military detachments around the countryside to act as a deterrent to possible future attacks. Primates in zoos were killed and their bodies incinerated. The Huntsman's Guild took an active role in most world governments, using their expertise to provide valuable insight into future incidents. Regrettably, notable figures on the side of the primates escaped, such as Gorilla Jesus and The Megachimp.
====== No Warning ======
The only organisation that had any idea of what was coming in advance was Aperture Security, who had been creating chimp shelters and training combat agents on the recommendation of experts such as Steve Irwin and Ed Sheeran for decades. They warned authorities before the event began, but their claims were largely dismissed as utterly improbable and unfounded. They provided public announcements during the early stages of the war on behalf of world governments.
