Quick question, do the zombies only spawn in one area now and no longer all across the map? Also, is there a way to make the patrol helicopter shoot at the zombies too?

Zombies will spawn around players provided there are enough players on the server (can be changed with the "Min pop for near player spawn" config option) and "Spawn near players" is set to true, if there are less players than the number set in config then zombies will spawn all over the map

I'm not sure about making the patrol heli shoot them, I'll have to look into it more.

Ohhh, okay thanks.
