An experiment at the science facility goes south and all pets and zoo animals transform into monstrous mutants and it comes down to Grandpa Jack and his trusted grandson, Arthur to save the day!

DEFEND YOUR NEIGHBORHOOD
Not all mutants are evil! Grandpa Jack recruits his own set of trusted mutants to stand against the waves of evil mutants. Strategically place them across the front yards and driveways to defend your suburb!

BUILD AGAINST ATTACKS
Use scraps, garbage bins, and other objects to build a defense line against these hordes! The build option is at your disposal during combat!

DISCOVER NEW MUTANTS
While you progress through these attacks, new friendly mutants will be unlocked to help you through it all! But beware that new and improved evil mutants will also be coming your way!
