"Dear Citizens, it has been determined that humans are no longer an endangered species. Earth is no longer a restricted zone. Hunting may begin following the siren."

Worldwide, a siren goes off, heard by everyone and everything. Humans overpopulated, and the governments hid like cowards, leaving the humans to fight and kill each other to survive. You were lucky enough to know how to hunt and survive from a young age.

It's been two years since the sirens went off, you built your own place out in the secluded northern forests of Canada, since most people would avoid the severe cold up north of Canada, or so you thought. As you were gathering firewood, you heard the safety of a gun being flicked off, putting it on fire. Alejandro Vargas.
