Zomboss Test Lab (疯狂博士; pinyin: Fēngkuáng bóshì; literal translation: Crazy Doctor) is a Brain Buster exclusive to Far Future in the Chinese version of Plants vs. Zombies 2. In these levels, there are plants on the lawn and the player has to defeat them in order to beat the level. They can use zombies to overcome and eat all the plants, similar to I, Zombie in the original game. Unlike I, Zombie, the player has to defeat all the plants on the screen, instead of eating the brains. Every plant that is killed by a zombie gives the player 150 sun.
This Brain Buster requires a very careful approach before directly placing a zombie on-screen. Like a military base that is impenetrable, study the pattern of the plants. Look for any passages to breach the base perimeters, then execute the final act. Now, the player must find ways to eat all the plants, Also, the player must have a good understanding of the abilities of both plants and zombies. For example, if a row has only a few Peashooters, it is safe to say that planting a Future Buckethead Zombie or a Shield Zombie will earn the player enough sun for another attack, and make them closer to completing the level. The player cannot take back zombies they placed, so they must plan wisely according to their amount of sun. Otherwise, the player will end up losing. The Mecha-Football Zombie is critical in the levels that consist him, as he can push back the plants.
When the 2.1 update was released, this was omitted in the international version of the game because of the new map layout. Its code can be found on The Cutting Room Floor website.
In this Brain Buster, all plants give 150 sun when killed, unlike I, Zombie, where only the Sunflowers gave sun when killed.
No plants in this Brain Buster are actually from Far Future.
