So basically, I was just speedrunning for fun for the day and all of a sudden, in this run, I noticed that there was no zombies spawning at the start of the round. I don't know whether I did something for this to occur or what but if I somehow am able to replicate this, it might help the speedrun community for the game.

I apologise there was no audio, for some reason the audio got corrupted or smth.
