Well would you look at that? Plants vs Zombies is out! It's been on Apple's iOS for what seems like forever and it's finally lumbered its undead self on over to our favorite mobile platform, Android! And, following the example of Rovio's Angry Birds RIO before it, Popcap has decided to release Plants VS Zombies on the Amazon Appstore first, it being free for the entire day today, today being May 31st, 2011. We've got a mini review of the game right here, too!
