If you like the genre of “Plants vs. Zombies” you will definitely enjoy Farmdefense for the BlackBerry PlayBook. The gameplay is almost exactly the same though here you have an army of robots trying to invade your farm instead of zombies. You defend you farm with some of those crazy plant weapons like Chili throwers and metal eaters.
Farmdefense does lag a bit when you get a large wave of attackers but so far I have been having fun playing it. For $0.99 Farmdefense is pretty much a steal in App World.
