Graveyard Ops

Graveyard Ops is a brand-new gamemode added in Plants vs. Zombies: Garden Warfare 2. It is similar to Garden Ops from Plants vs. Zombies: Garden Warfare but only with the zombies on the defense, and the plants on the attack. The main attacking plants are Weeds, along with other class plants (like Cactus), because of this; when a new wave starts, the announcer will say "The Plants Are Growing" and all the plants will emerge from the ground.

Bosses:
So far we have only seen the Giga Torchwood, this will most likely mean there will be a regular version of this boss
