Launch a volley of explosive garlic.
Try to use this against large groups of zombies to whittle down all of their health (as this ability does splash damage) an assist your teammates in vanquishing them.
Try not to clump up with other zombies if a Garlic Drone is near. If you hear one using this ability, you have less than a second to either sprint away, hide, or try to shoot the Drone down. If you choose to flee, try to zigzag so you don't get hit. Only attempt to shoot the Drone down if you aren't the one being targeted.
