Ah. I don't think that changed a lot up until A16 though with the awful sleepersystem.I'm playing A15 now and nights are something we stay indoors huddled up, and cities are dangerous as f$£, Have zombie density to 150% and they're litterally crawling out of houses when fighting them in the streets, I often count up to 40ish zombies at a time for the fights.
I started fighting a few zombies on a road a few 100 meters from a small town at day 1 with a crap club. It turned very fast to a fight for the life as more and more zombies roamed in from around and I had just time to kill the last few and panic-dig a small hole in the side of the road and hide for the night hoping I wouldn't be sensed.
I think we're at day 5 now and I have somewhere between 350 zombie kills, my friend 200 something.
So amazing in contrast to now, when we're out and walking and looting houses in the towns in the middle of the night with no fear.
(except when we attack a boar, that's the only monster we are scared off

)
