New Things 

creep combat All creep will now target and shoot at towers. Towers have armor, shield and health when a creep shoots at a tower damage will be dealt to the towers shield first. After the shield breaks all damage is dealt to the towers health (minus the towers armor)shields can recharge after a given time, hp will not regen and when a tower loses all of its hp it is disabled and must be sold or repaired. Each time a tower breaks it has an increasing chance to be totally destroyed.
