Serve and Volley is a Super Mix Mode in Plants vs. Zombies: Garden Warfare 2. It is a variant of Gardens & Graveyards where players can only play as Chomp Thing on the plants team or Tennis Star on the zombies team.
The mode functions the same as Gardens & Graveyards, however with only Chomp Thing and Tennis Star being playable. Players knockback their opponents whenever they damage them, and everyone has zero overheat.
Chomp Thing and Tennis Star are spawning! Rush the enemy base and claim victory over the battlefield.
As Chomp Thing
Note that the Infini-ammo Crazy Setting does not only affect players, but also spawnable plants and zombies. This makes Scaredy-shroom extremely powerful in this mode, due to his high damage and accuracy.
