Across the Lawn

Across the Lawn (围追堵截; pinyin: Wéizhuīdǔjié) is the third Brain Buster of Castle in the Sky in the Chinese version of Plants vs. Zombies 2. It is unlocked after beating Day 20 and opening its corresponding gate with 5 keys.

Its concept is extremely similiar to Fright Theater. The main change is that now there is a trail of arrows representing the path where zombies go and it can be changed by placing wooden boxes. However, they can only be placed on determined tiles and cost 100 sun each. The rest is almost the same. The player has to place certain plants already chosen on metal and wooden crates and upgrade them with sun that every zombie drops to get ready for menaces with enourmous quantities of health without letting them reach the end of the pathway. There is also a limit of how many zombies can get to the goal and the level is lost when that limit is exceeded.

Strategy
This is an extremely difficult series of minigames. Not only high-health and high-speed zombies come in quicker than you can set up defenses, all of the zombies give small sun which is not enough for the player to upgrade his plants and plan a defense consistently. What's worse, all your plants will only actually have 1 column of range due to the level design, unless when the player constructs a long enough path for the zombies to be delayed and attacked, which is extremely difficult as most plants cannot attack sideways. Even if the player manages to construct a coherent defense, Zombies will still invetably get past and using the Cuke Power-Up multiple times is virtually unavoidable.
