Maneira fácil de matar 53,595 zumbis
INTRO: Killing 53,595 infected is a daunting task. Think about it. In an easy campaign, your team may kill around 1,200 zombies in half an hour. Splitting that evenly among the four teammates (for the sake of simplicity), and you only end up with 300 kills. Reaching 53,595 kill is going to take a very, very long time.
