We know that above a certain total amount of zombies the only places where zombies spawn is in tiles with neighboring zombies.
Would it be a good idea to start killing zombies strategically from the start, to try to keep some parts of the map zombie-free? Has anybody tried something like that before? It should also reduce the number of tiles with many zombies on them, reducing the chance of people getting stuck outside.
I'm mainly wondering if it is even possible with the mostly crappy weapons you have in the beginning, and if the efforts would pay off. If I want to try it I'll have to convince my next town that it is a good idea.
