These wandering hordes are something i didn't like at first, having then daily? was a massive NO! from me. So i waited until i played enough of the experimental to see what my final thoughts were, i have played a good bit now (around 40-50 hours)
Wandering Zombie Hordes - i now do not mind having these, appearing daily and at random, as long as they spawn at day time, you have enough time to react according, even if they sneak up on you without a sound!
Wandering Dog Hordes - only seen these once! i was building away, working on my current base, my character got hungry, so i had to decide to keep working away or go and eat now, so i decided to eat and start crafting more stuff in my work bench, now my base is fully open ATM while i am working on it, so soon as i step into my forge area BAM! around 10 dogs where running right for where i was standing, i only heard there growls AS they got to the area i was! this got me thinking. is the sound an issue? a bug? or are these hordes suppose to be silent? because if i did not decide to move at that moment, i would of died.
