In my map currently, there is one small issue that makes it go from difficult, to extremely easy and that's zombie spawning. For my first and second zones (which are relatively small) zombies seem to spawn at quite a normal pace but once I buy the debris to zone 3, it seems after while it can actually take 5-10 seconds before a zombie will rise out of the ground. I would assume this is because zone 3 is quite big, but I just wanted to be sure. I mostly have all risers (because my normal ones were just standing there, and plus it's pretty open from where I imagine the location of this map to be, which is like area 51 or a restricted area of some sort). Thank you to anyone for any sort of help.

Inside zombiemode.gsc search for this line

// Spawning
	set_zombie_var( "zombie_spawn_delay", 				2  );

And change that number to hoow many seconds you want it to take for a zombie to respawn.

Thank you so much!
