Brainball

Brain Ball is a competitive mode in Plants vs. Zombies Adventures. In it, players hide brains in their town buildings and defend them. They can also attack other players with zombies to get their brains. It is a different environment, so a different test account is created for players. Players are put in a pool of up to 100 different players that have unlocked the same lots. The player with the most brains on the leaderboard wins currently unknown prizes. This mode introduces new VIPs, the Beetboxer and Acespearagus, along with three new buildings, the bank, statue, and space probe. Plants have shorter harvest times. Since the Brain Ball test client account is different from the Plants vs. Zombies Adventures account, progress so far is different. Every test account starts with 1,000 Gems, 50,000 Zombucks and 50,000 Coins.

In order to launch attacks on other players, you must first clone zombies in the Zombie Cloner, in a similar way to how you grow plants. There are three waves in each attack, and in each wave you can choose a cloned zombie to use, and that zombie will then attack along with several other zombies. After each wave, a new grave will appear at the farthest point the zombies reached, and that is where the zombies will spawn in that wave. If you fail to invade the building within three waves, you lose. During combat, you can collect fog that falls from the sky, and spend it on boosting zombies or stunning plants (each use costs 15 fog). This fog works similarly to sun when playing as the plants.
