Cheater! Cheater! was a secret achievement in Plants vs. Zombies Adventures. It required the player to use a debug cheat button. It was impossible to obtain normally on purpose, as this achievement was used to identify players who hack Plants vs. Zombies Adventures, who will then have their account disabled on Facebook.
- It was the only achievement in the whole series that was impossible to obtain legitimately, and was used as a trap to identify hackers immediately.
