If you want to allow humans to use CS buzones easily (ZP 4.3 Fix 2 and later), just add these settings to your server:

zombieplague.cfg:
-----------------
zp_remove_money 0			<--- Enable CS money
zp_buy_custom 0				<--- Disable ZP custom buy menu (optional)
zp_buyzone_time 30.0		<--- How long humans will be able to use buyzones after spawning (in seconds)
mp_buytime 99				<--- Prevent CS from messing up ZP buytime

zombieplague.ini:
-----------------
Add "func_buyzone" to [Objective Entities] section (list of entities automatically removed at map start)
