Cheat Engine is not just dedicated for Plant versus Zombie Adventures or Facebook game. Indeed, it is usable on all kind of processes. The core concept is to find out a specific value and alter it. In other words, if it is used properly, you can change any value to a high number. You can change your Coins, Zombuck, Sun, Fog, item quantity, number of Plants, etc. to an unlimited value of 999999. Since PvZ is a very new Beta game and there is such loophole, you can pull this trick unlike older games like ChefVille.
