Zombie invasions meet a generally unprepared. Hardly one evening, looking out the window already wobbling beasts lounging around the house with bloody fingernails scratching at the door.
The entire better if one has exceptionally prepared yet hold fast onto buttons and tons already a wrecking ball whizzing past the wall and smash the zombie army in its individual parts.

That is the starting point for the latest Tower Defense Variant Zombie Smash! Game of doctors. 31 days for you, you must defend it and then you have survived the invasion. You sit in the role of Joey alone in your house and defend yourself against the moldy brood. From the left or right (and later increasingly shaken simultaneously from both sides) funny animated cartoon monster on you. The range of attackers ranging from regular zombies on helmeted soldiers until lightning gun men towards women and beefy undead that are too heavy to lift them.
