Great Game
A good example of just how addicting a flash game can be, make it a little longer or add some more replay value and put in some simple 3d graphics and I could see myself paying 2 bucks or so for this.
My only complaint is with the special zombies, there just wasn't enough variety in them, they all kind of felt the same after awhile not much strategy involved in the placement of the zombies really other than placing the tank down around dangerouse mobs.
This is about as close to making a perfect flash game as you can get, kudos. For those of you wanting to know where to unlock the special zombies here ya go..
