Once again, conquer the world and one of the new features in this sequel is the alliances in which you can control them to attack various parts of the world.
A great combination of zombie shooting and 'match-three' puzzling with an atmospheric (and bloody!) horror theme. Match up and pop the monster heads before they reach the barricade. Use grenades to get out of a tight spot.
Enemies are approaching closer and soon they will reach your base. Stop them by strategically placing from defense armies to turret towers in their way.
