The idea would be as you make noise, some zombies come from random directions to "investigate". They spawn, so the idea is that the zombies were far enough away to hear but too far to be seen "in the spawn zone".
This should be rarer if the noise is spread out, but ramp in likelihood if more noise is made.
This should be throttled so it cannot happen repeatedly, and/or have a max number of zombies that can be spawned this way in a short period of time. Don't want the people fighting these 360 zombies to spawn MORE 360 zombies. They should eventually run out
