Zombie Squad has members all over North America and members in countries all over the world , including the United States , Canada , UK and South America among others . The success may be due in part to the synergy between two phenomena that have emerged in the new millennium : A resurgence of zombies in pop culture , with hit video games ( the '' Resident Evil '' franchise , '' Dead Rising '' series , '' Left 4 Dead '' , '' Stubbs the Zombie '' , '' House of the Dead '' series , etc. ) , literature ( '' Pride and Prejudice and Zombies : Dawn of the Dreadfuls '' , '' The Walking Dead '' franchise , '' World War Z '' , '' The Zombie Survival Guide '' ) and films ( '' 28 Days Later '' , the '' Resident Evil '' series , the '' Dawn of the Dead '' remake , '' Shaun of the Dead '' , '' Land of the Dead '' , '' Zombieland '' , etc. ) combined with a renewed interest in disaster preparedness in the wake of natural disasters ( 2004 Tsunami in Indonesia , Hurricane Katrina ) and high-profile terrorist attacks ( failed millennium plots , 9/11 , 3/11 , and the 2005 London bombings )
