Zombies[]
These things are the best unit in the whole game (Well when upgraded)
It only takes One to take down one angel and two to take down a borg (cyborg)
The can have up to about 2300 HP and its dumb when there right in front of a golden cannon
(Black snow Mountain level 8) gets really hard when one hero has to solo 1-2 snow monster(s), 2 Zombies, 2 golden cannons and shamans!
(I also wish we could recruit these beasts, lets face it, even though the slow, with a priest behind it, it kills all!)
