What Zombies should I use to conquer cities effectively?
Personally, I start off with these zombies (all max upgrade):
Zombie > Meathead > Tentacle Zombie > Zombie Hero

Zombie conquers South Pole, North Pole and Africa.
Meathead conquers Canada, South Asia, South America and Central America.
Tentacle Zombie conquers Australia.
Zombie Hero conquers remaining territories, China, Russia, Europe and United States.

To avoid losses of zombie soldiers, you need to have more soldiers than the defender.
Recapture cities or towns if human had taken over before it grows stronger.
Hire more commander to enable more soldiers to invade highly defended city.

If you chose hardest difficulty mode in Zombies Inc, I suggest you check out the list of Zombies Soldier below. There are certain types of Zombies which are very effective within certain territories such as Tentacle Zombie, Cinder Zombie, Plague Zombie and Mobster Zombie. Zombie Hero is an exception as its a legendary Zombie that works best in all territories.
