Dear Community, i would claim i am a relatively experienced Zombies Player and have been playing casually from time to time since Black Ops 1. I came across a few World Record Videos from Players who manage to reach Rounds 100+. Impressive stuff. But i noticed that (especially in Outbreak) players can kill Zombies Round 50+ with a single shot. Me unsing the Hauer77, max Weaponlevel, built for maximum firepower, Legendary rarity and triple Paped can barely kill a regular, unarmed Zombie in Round 7 of Outbreak. Am i doning anything wrong here? How come people can kill even armed zombies sometimes with a single shot? Here is a quick example. Round 1000. Still being able to kill Zombies like on Round 2 # : Plus they dont even run as fast as they do in my game. What is all of this about? Thanks for answers!
