Zombie Vanquished is an achievement in Plants vs. Zombies: Garden Warfare. To get it, the player must play as a plant and vanquish a zombie player in any competitive mode.
Strategies
Team Vanquish can be a good way to earn this achievement, because vanquishing is the goal of this mode. And if the player plays as a zombie, he or she does not have to walk all the way to the plants' location, unlike Gardens & Graveyards.
