CURRENT CHALLENGE
CHALLENGE 12: Cleopatra, Lich Queen of the Nile
Duration: October 16 - November 13
Get into the spooky Halloween spirit with this spine-tingling Zombie Defense scenario! As Ptolemaic Cleopatra, you alone have the power to command an army of the undead. For this challenge, Cleopatra's Warriors can convert Barbarians (all of whom happen to be the risen dead), but Warriors are the only Military Unit she can train. Rally the roaming hordes of zombified Barbarians to fight on your behalf and rule the world as an almighty Lich Queen!
