Forward my Zombie Army. LOL. I managed to get through hard, not just in 71 days, but also with 701 Zombie Heroes and 999 of all the other types of Zombies. Only started red once, other than that, I am Bill Gates of the Zombie World. :P
Now that I have gloated about my accomplishment. This was unbelievable well constructed, thought thoroughly, money really talks here, and bites. Not a single bad that I can think of to say about this game. Keep up the good work.
