Hard to tell. Like, currently have 90k creatures total killed by my survivor; around 24k of those irridated wanderers, and let’s generously say that maybe 10k-20k of those were non-zombie creatures. It’s almost the end of my survivor’s second year, around 140 days left (91 day seasons). That said, chunks of the time spent so far were spent not killing, so it’s kinda hard to tell how quickly you can empty a 16 size city.
