Qin Shi Huang Mausoleum - Level 2-4 was the final spin-off level of Qin Shi Huang Mausoleum - Level 2-1 in Plants vs. Zombies Online. It is a conveyor-belt level. There was one pathway. When this level was finished for the first time, the player would get three Sunflower Puzzle Pieces. To get all three stars, the player had to not let the zombies trample the flowers nor lose any lawn mowers.
- The only difficulties of this level are the pathway, which prevents the player from planting on them, and the flowers if they attempt to earn stars.
- The Pomegranate-pult is a new plant in this level. It's a stronger version of Cabbage-pult, making this level even easier.
- Simply try to plant as many given plants as possible. Pay attention to Cavalry Zombies and the pathway if you want to earn stars. Do as you did to complete Level 2-2.
