Qin Shi Huang Mausoleum - Level 4-4 was the third and final spin-off level of Qin Shi Huang Mausoleum - Level 4-1 in Plants vs. Zombies Online. It was a Carrot Rocket Launch level. There were no pathway, and there were pre-placed Carrot Rockets on the lawn. When this level was finished for the first time, the player would get 100 upgrade sun to upgrade certain plants and three Spring Bean Puzzle Pieces.
The player could fire the first Carrot Rocket by using "A" button, the second one by using "S" button and the third one by using "D" button.
In this level, there was a wind mechanic that affected the trajectory of rockets.
- This Brain Buster can be harder than the previous ones, since the player needs to control three Carrot Rockets 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 Rockets 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 Rockets, but watch out for the wind.
