Blue Cocker - Welcome - extension 2: Zombie Invasion and ice cream truck

In this second expansion, you'll have to sell as many ice creams as possible in your allotments, while building them up cleverly.
Be careful not to hang around too much on your ice cream truck tours. Be careful not to drag your ice cream truck around too much either.
You'll also find yourself in a dark universe, where building a beautiful neighborhood will sometimes be the least of your worries. In fact, you'll need to protect your new homes from the zombie hordes that roam your region.
Will you give up homes to protect others, or will you defend everyone?
