This is a problem, my opinion on it is. -Random hordes beelining your base is lame, especially if you don't build a base. So a player decides to move from house to house, living quietly and cautiously. That wouldn't be an option if you get a homing horde that already knows where you are. It kills playing style options, aside from that... building a base is 100% safe atm anyways. Until zombies can break walls... I really don't care how many zombies scurry outside of my base (not entirely true, a horde of nonsensical camper zombies constantly sitting outside my walls for no reason what so ever would by highly annoying.) I could picture a few zombies wandering into the area, but if I don't do something to get there attention theres no reason for 100 zombies to camp me like its black friday. -Now, I do think zombies should migrate. Moving from area to area... occasional gatherings of zombies moving to less dense areas. Additionally, once the military containment fails, there should be huge migrations of zombies crossing the map and repopulating areas. -Please! do not make it where zombies will magically pop up in my secure, corpse free base without having them break through a wall. I don't want to open the bathroom door and find a zombie in there unless there's a way for them to get there.
