Plants vs. Zombies: Garden Warfare 2 is a third-person shooter, similar to Garden Warfare. Gameplay largely remained the same as its predecessor, with the addition of 10 (6 are immediately accessible, 2 which must be unlocked through a series of tough trials and 2 which can only be played within the game's endless mode) new plant and zombie classes, a zombie version of Garden Ops, titled Graveyard Ops, and a new mode called Herbal Assault, a swapped version of Gardens and Graveyards where the Zombies must defend the bases and prevent the Plants from capturing them, which supports a maximum 24 players per game. Different classes have different abilities. Most characters and modes (Team Vanquish, Garden Ops, etc.) from the original Garden Warfare returned, as well a new "remix" music from the original Garden Warfare for the Zombies. New abilities for returning characters were also introduced in Garden Warfare 2. The new plant characters are Citron, Rose, Kernel Corn and Torchwood. The new zombie characters are Imp, Super Brainz, Captain Deadbeard and Hover-Goat 3000. The old plant characters are Peashooter, Sunflower, Chomper, and Cactus, while the old zombies are Soldier, Engineer, Scientist, and All-Star.Unlike the original Garden Warfare where players can play solo only on Garden Ops, via private mode, in Garden Warfare 2 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. An internet connection will still be required as in the first game.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 known as Flag of power matches against artificial intelligence at will. When playing Backyard Battleground, the game will send waves of enemy heroes, although the game will also send crates, containing either an AI ally or coins. There are also plant pots or places where the player can build either plant turrets or Zombie bots. 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).
