Throughout the stage, increasingly strong Zombie enemies are sent out from the enemy base, starting with Znache and ending with terrifyingly strong Zories. Kory appears when the base is hit.
Sniper the Cat power up can shoot the Zorys, causing them to not burrow. A hypermaxed Manic Flying is definitely an valuable asset in this level, also try to stack Manic Macho Legs to clear peons to allow the sniper the cat to hit powerful zombie enemies.
You can also clear this stage by spamming units with decent damage and time between attacks (Like Kasa Jizo or Baby Gao).By stacking this units,you'll deal enough damage to knock back zombies when they are about to borrow,making them to not borrow.Also,they will deal a lot of damage to kory,reducing his health.A strong uber is racommended to take out the kory quickly in case he plows your defense and raches to your base.
