films were seen multiple times throughout the episode. The established rules used in this episode are that the zombie virus has the potential to spread to a vampire, sunlight will affect the vampires, the vampires can only be killed by removing/destroying its head or heart or by bleeding out, and the zombies can only be killed by destroying the brain. To determine how many zombies a vampire could kill before getting overrun, Leif Becker, expert martial artist and world champion speed board breaker, tested metal claw gauntlets designed by Dave Baker to simulate a vampire's razor-sharp claws. He was surrounded by 12 zombie dummies on pulleys, and ripped apart 9 out of the 12 zombies targets. Multiplied by 6 (to simulate the Vampire's superior strength and speed), that would be 54 zombies killed out of 72, with an average of 63, resulting in the ratio of zombies to vampires (63 to 1). For close range, in order to get a baseline pressure reading, the zombie bite was simulated by a 100 lb rottweiler, named "Joey", that bit down on a load cell hidden in an attack sleeve which resulted in 255 lbs of pressure. For the vampire bite, an alligator, named "Ripper", was brought in to chomp down on a 10 lb load cell between two blocks, which resulted in 1,723 lbs of bite force. Then the forces were fed into an automated chomper designed by Geoff, changing the bite force and teeth for each creature. The zombie teeth killed a simulated vampire through bleed-out in 2:22, and the vampire teeth destroyed a zombie brain in 5 seconds. For mid-range, the Vampire claw was matched against a horde of Zombie hands. For the Zombie hands, three world-class strongmen were blindfolded (to simulate the Zombies' random attack pattern) and instructed to rip at a ballistic gel torso until they removed the heart, killing the vampire in 58 seconds. To test the Vampire claw, one of the aforementioned strongmen slammed down on a pressure mat, the force generated was multiplied by 6 (to simulate the Vampire's super strength), generating a slash force with 8,820 lbs behind it, enough to penetrate a zombie gel head, destroying its brain and killing it in 1.07 seconds. This is the third episode with no long-range weapons. This is the first and only episode of season 3 where the least effective weapon was not in the same
