also, answering the other questions in your ‘holywalloftext’:
if you play static spawn, yes, it’s easy to clear a town. Dynamic spawn uses sound to generate an impossibly huge amount of zombies over time as you continue to make noise. This ‘may’ be more of what you’re after.
dynamic spawn CAN be depleted, but again, this is a MUCH larger amount of zeds to deal with so there’s that…
In dynamic spawn a gunshot could very well get you killed…they come from EVERYWHERE.
and shotguns are even worse, generating what seems 20-30 zeds every time you shoot. so yeah
