A fun game but the developers try desperately to nickel n dime you. As you progress game becomes completely off balanced with a huge advantage to the zombies (some being almost invincible ha). I would happily pay $2-$3 bucks up front for the game but in total to unlock would cost $50+ which is just insane for a silly little game.
