Brains on a String

The zombie apocalypse is upon us and people are dying everywhere.  It is just a matter of time before you die as well.  Fortunately, there is a way to control the zombies and that will benefit you since you can dictate where do they go.   The idea here is to lead the zombie to where the humans or animal is.  Once that all the humans and animals are all gone then you can proceed to the next level.  There will be another zombie up head in the coming levels, but, they won't be your friends as they will be fighting against you.
