Plants vs. Zombies: Garden Warfare 2 is a third-person shooter, similar to Garden Warfare. Gameplay will largely remain the same as its predecessor, with the addition of 6 new plant and zombie classes, a zombie version of Garden Ops, titled Graveyard Ops, and a new mode called Herbal Assault mode, which supports up to 24 players. Different classes have different abilities. Most characters and modes (Team Vanquish, Garden Ops, etc.) from the original Garden Warfare will be returning. New abilities for returning characters will also be introduced in Garden Warfare 2.
Unlike the first game, the game will not require an Internet connection to play and every mode in the game can be played solo. Split-screen multiplayer, private servers, twelve maps and forty different characters will be supported at launch. Free additional content will also be released regularly upon the game's release.
A new mode called Backyard Battleground is also introduced. It serves as a hub world that is free for players to explore. In Backyard Battleground, players can access portals that are connected to missions, view unlocked characters' bobbleheads, collect collectibles scattered in the world, and join King of the Hill-style matches against artificial intelligence at will. A shooting gallery and moon-based missions are also featured.
Plant and zombie variants the player earned in the original game will automatically transfer to this game. The UI has been improved, with Crazy Dave and Dr. Zomboss shown talking in 3D model of themselves (rather than appearing as 2D designs from the original Plants vs. Zombies).
