FarCry 5 Zombies DLC "DeceaZed to ExZist" Achievement/Trophy Guide

This achievement sucks, a lot. There is an AFK method as l'm sure you (yes you reading this) know of, as you've probably been looking up ways to unlock this achievement fast. Truth is, there is no "fast" way, just brain rotting grind! So, instead of sitting AFK for 8 hours farming 6 kills every 30 seconds or so, this is the most efficient way to get this achievement in 3 hours or so! (If you're quick). Good luck! (I'd highly recommend listening to a podcast or having a video playing in the background as a sort of distraction. This is pure rotting of the brain to have to run through repeatedly)
