Flag of Power

Flag of Power is a new King of the Hill-inspired game mode in the Backyard Battleground and is located in the direct center of the map. The player, playing as a plant or zombie, can raise the flag in the middle of the map. Once the player raises the flag, their damage will be amplified by four and their resistance to damage will be four times higher too. A large ring will appear around the flag, and the player must stay in the ring to ensure the flag stays up, as if they leave and an opponent is in the ring, the flag will start to lower. Four plant pots or Build-a-Bot stations will also appear to help you protect the flag.

Crazy Dave or Dr. Zomboss (depending on which side you are on) will unleash waves of AI foes, from normal AI to AI heroes. Between each wave, a reinforcement crate will be dropped in a random place on the battleground, and the player can break it to either get AI helpers or coins. After each wave, the player will be rewarded with lots of coins. After Crazy Dave or Dr. Zomboss has unleashed the last wave (a boss wave), they will start an endless mode, and an endless amount of AI foes will appear, from regular AI to AI bosses, just to see how long the player can hold the flag. If the opposite side manage to take down the flag by staying in the circle for a long time and the player is not, the game will end, and the player will have to fight off the remaining AI.
