Kill 3 spitter zombies
Spitter zombies can be found level 2 battles and higher. They're slow, but their spit is so rich with acidic bile that they present a threat even at a distance. Pick them off early, use evasive maneuvers, and remember you can take cover behind trees.
You need to personally kill these spitters, and also survive the battle.
