The laboratory was a part of Battle in the Chinese version of Plants vs. Zombies 2. In here, the player could upgrade their Training Camp, their defense area and much more.
Usage[]
The Laboratory is where all of the important things in the player's PvP Area could be upgraded. There is a menu screen where player can choose what to upgrade.
- This shows the level of the the object. In this example, it shows that this PvP player's base is at Level 4.
- This tells the player what they are selecting. Here it shows them selecting the base.
- Here is the scrolling bar. The player can upgrade 5 things in total. The player can upgrade their entire base, their total amount of sun, their capacity of training zombie troops, leveling up their zombie troops and leveling up their power ups.
Leveling up[]
The player could only upgrade one thing at a time, and it mostly took a hour or two. They must use 
to upgrade your objects. In the example (the first image in the gallery), it needs 600 to upgrade to the 5th level. On the top, it shows that the player will get 5300 and 2600
every 70 hours. Next to it shows what the player will get if they upgrade their base.
