I love the Zombie he’s not only fun because he’s something new in the game!
But he adds a new dynamic: Turning or Zombifying your Enemies!
But more importantly his presence makes other obsolete elements of the game becomes useful and necessary again!
The Zombie’s weakness to Fire makes Firebolt Towers and Pyromancers become relevant again, even Gargoyle Towers!
I do not want to see the Zombie go with Halloween. I want Flare to make the Zombie a year-round aspect of the game!
