Graveyard Ops

Unreleased Graveyard Ops is a game mode 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 attacking side. The main attacking plants are Weeds, along with other hero plants (playable plants, like the first game where playable zombies can be seen). When a new wave starts, the announcer will say "The Plants Are Growing," rather than "The Zombies Are Coming," and all the plants will emerge from the ground. Peashooters will debut at Wave 2, Cacti at Wave 3, Sunflowers at the Boss Wave and Chompers at the Landing Zone time (additional wave).

Bosses
So far, only the Giga Torchwood has been revealed. There will likely be a regular version of Giga Torchwood, similarly to Giga Gargantuar and Gargantuar.

End objective
The end objective of a Graveyard Ops round is to rush to Zomboss' blimp while the map self-destructs, just like when Crazy Dave leaves to pick up the plants with his RV in Garden Ops (aka Landing Zone), with Plants rushing towards you. It is called an "Explosive Escape" when the Imp and Z-Mech use their eject ability to launch the Imp onto the blimp.

Trivia

 * Graveyard Ops was originally going to be included in Plants vs. Zombies: Garden Warfare.
 * There is a oddity that if the user looks at the spinning panels in the slot machine, they can see zombie icons from Garden Ops regular mode (like Disco Zombie icon, tombstone icon, etc.) but the plants will show when the plants are clearer to see. This possibly means the spinning panels will be changed in the final release possibly because they are still working on bosses in the game (since it is in development, they've only developed Giga-Torchwood and the plant versions of the random assortments of zombies shown in Garden Ops boss waves).
 * If someone presses pause at the right time, they will see the zombie heads are all Super Boss Waves.
 * Before the boss wave, Crazy Dave shows up before the Slot Machine spins, similar to how Dr. Zomboss shows up before the slot machine spins in Garden Ops. But he doesn't really prepare the zombies for this unlike Dr. Zomboss, he just states how the lever works (but he does make it work). Crazy Dave's face doesn't show up near the slot machine when it spins, unlike Dr. Zomboss's in Garden Ops.
 * There isn't a timer shown when Dr. Zomboss attempts to leave with his zombies, unlike Garden Ops. Again, it may change.
 * However, a more recent video shown the time, however the time required to get to the landing zone is 30 seconds less than in Garden Ops.
