Qin Shi Huang Mausoleum - Level 4-4 is the third and final spin-off level of Qin Shi Huang Mausoleum - Level 4-1 in Plants vs. Zombies Online. There is no pathway, and there are pre-placed Carrot Missiles on the lawn. This is a mini-game level of the world. When this level is finished for the first time, the player will get 100 upgrade sun to upgrade certain plants and three Spring Bean Puzzle Pieces.
The player can fire the first Carrot Missile by using "A" button, the second one by using "S" button and the third one by using "D" button.
In this level, there is a wind mechanic that affects the trajectory of missiles.
- This Brain Buster can be harder than the previous ones, since the player needs to control three Carrot Missiles to defeat the zombies.
- Iron Helmet Sergeants can cause trouble since they come in groups and take three explosive carrots to kill. This might lead the player to lose some Carrot Missiles easily.
- If you are still having trouble, use Squash, because it may prevent you from losing stars.
- A trick is to simply wait until the zombies are close enough, then use A, S and D buttons at once to fire all of your Carrot Missiles, but watch out for the wind.
