Plants Vs Zombies is free today on the Amazon Android Marketplace, so for everyone with an Android phone, well you are a fool if you don't download this very fun game RIGHT NOW. Plants Vs Zombies is a tower defense game made by Popcap, makers of Bejewled, Peggle, Chuzzle, and lots of other fun addicting computer games. I have Plants Vs Zombies on steam and it's lots of fun to play on computer and being able to have it on my phone so I can play it where ever is very awesome. I highly recommend this addicting tower defense game.
