Zombies are marching outside your house! You do not have a weapon but you do have a baseball bat to shoot balls at the waves of undead! Your wife who is the pitcher who throws the ball from the balcony and wait until it bounces on the ground to hit it with your bat towards the zombies to strike them. Stop as many zombies as possible by hitting them on their heads for double score. As you advance in Zombie Baseball a secondary bat will be available.
Press A for primary bat. Press S for secondary bat.
