Tit for Tat (以牙还牙; pinyin: yǐyáhuányá) is a Brain Buster exclusive to Dark Ages in the Chinese version of Plants vs. Zombies 2. It is very similar to Dark Alchemy. The player must fight against zombies with the help of Hypno-shroom. To unlock this Brain Buster, the player must obtain 4 Dark Ages keys.

Trivia

• This is the only Brain Buster to feature two identical plants: normal and costumed Hypno-shroom.
  • Only Hypno-shrooms that are given Plant Food with costumes will transform zombies into Gargantuars in the player's favor.
  • If the player has already costumed Hypno-shroom, then the normal seed packet will give a costumed plant.
• This, Cannons Away, Oak Archery, Gluttonous Hungry Guacodile and Bulb Bowling are the only Brain Busters that feature one plant.
