[2023] Old Question back to life: Range on Zombie senses

So, this may not be intuitive, but the game spawns zombies (specifically screamers) when the activity map in a chunk (area) gets too high. It’s computed for every chunk of the map, independent of any particular entity. The screamer’s task once spawned is to move to the chunk of the map with high activity. There are strategies to combat screamers, but staying ‘out of range’ isn’t really a concept that applies here.
