Qin Shi Huang Mausoleum - Level 8-4 was the third and the last spin-off level of Qin Shi Huang Mausoleum - Level 8-1 in Plants vs. Zombies Online. There were two pathways. When this level was finished for the first time, the player would get 50 upgrade sun and three Bloomerang Puzzle Pieces. To get all three stars, the player had to not lose more than 3 plants, and not lose any lawn mowers.
- The Archer Zombies and the Shield Guardian Zombies, especially Archer Zombies who appears as a threat in this level, can make the player lose their star if they don't defeat them quickly.
- Do what you need first. Kill the first zombies with cheap attack plants. Don't forget to use Sod to plant on pathways.
- Archer Zombies appear a lot in this level, that means it's a perfect time for Carrot Rocket. Plant Peashooters, Carrot Rockets and an another attack plant from your friend, to build your attack. Upgrade the Sunflowers into Twin Sunflowers and the Peashooters into Repeaters if you can. Plant Wall-nuts to protect you from Archer Zombies and Shield Guardian Zombies.
- When you're in trouble, use Plant Food.
