Bigfoot and the Four Horsemen

If you are looking for a story with nice friendly Bigfoot, this isn't it. This is a chronicle of the apocalypse that everyone got wrong - the Bigfoot Apocalypse.

As our story opens, we find the old Silver Mine beneath Billings Mountain under siege by the Beasts. Four Hell tanks defend what remains of humanity in a tenuous truce with the surrounding hordes of Bigfoot, formerly the residents of Billings Valley, members of the National Guard, and Bigfoot hunters who got more than they bargained for.

Dr. Cross, the mad scientist who accidently unleashed the Virus that's turned much of humanity into ravenous rather tall beasts with big feet, has nearly found the way to control the Beasts-and once she does the truce will end-blood thirstily.
Luckily, the Huntington Academy's impromptu taskforce, led by Cadet Captain Krissy Smith in her modified World War II-era T-34 tank, has reinforced the surrounded survivors with her own ragtag group of survivors in tanks, mini-vans, school buses, cars of every variety, and support crews from the Huntington Toy Factory.

There are also rumors that there are four pale horses now in residence in the underground sanctuary. Each with a rider waiting to lead the army of teenagers and seniors against the Beasts.

You say, you don't believe in the Four Horsemen? You likely didn't expect the Bigfoot Apocalypse, either...
