Anyone else really addicted to zombies?
Highest solo round: 58
Highest solo exfil: 55

try out the pump shotgun. fully upgraded makes first 60-70 pretty easy

zombie HP and stats cap at wave 52 iirc
so as long as you get that far, the only limiting factor is ammo consumption while the waves get longer and reload speed while the zombies spawn speed is increasing

Yeah we mostly have been working on getting dark aether camo so not really pushing the high rounds that hard!
