While Plants Vs. Zombies was shown on the PlayBook during CES, EA announced today that the popular game is now available on BlackBerry App World.  With all three versions of Angry Birds as well as Cut The Rope having launched on the PlayBook, the tablet now has all of these popular titles.  It is important to note that these games are not Android apps ported over to the PlayBook.  Instead, they are native PlayBook apps, making the game play much richer and more smooth.  The link to download Plants vs Zombies is not yet available, but will likely go live in the coming hours.
