Qin Shi Huang Mausoleum - Level 4-2 was the first spin-off level of Qin Shi Huang Mausoleum - Level 4-1 in Plants vs. Zombies Online. To play this level, the player had to unlock the star gate for 4 stars. It was a Brain Buster and it was a Carrot Rocket Launch level. There were no pathways, and there was one pre-placed Carrot Rocket 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 Carrot Rocket by using the "A" button or simply clicking on it. It will fire far away or close depending on the bar on it high or low.
This level also introduced the new wind mechanic that affected the trajectory of rockets.
- This mini-game should not be too difficult if the player is familiar with its function. Moreover, Squashes make the level easier.
- If you are still having trouble, use Squash.
- A trick is to simply wait until the zombies are close enough, then click/use A button twice at once, but still, you have to watch out for the wind.
