9 Heros Defence

To. my beloved animals.
Dr.Z has turned the entire humankind into zombies.
The humankind’s last hope is the babies kidnapped by Dr.Z.
All we have left is you, who are not infected.
I will awaken your hidden power.
You have to save the babies no matter what.
The fate of the world is in your hands.
I wish you become the heroes who will save the world.
From Dr.K
