plants vs zombies

Plants vs Zombbies is a very interesting computer game.Just search plants vs zombies on google and you can find it.A screen will display 'buy now'but that's something a fool will do.Scrool down and there will be something like'download for free' .Thats what you're looking for.The game is about defending your house from zombies that are trying to eat your brains,using plants like the peashooter,sunflower,mine,wall-nut.I have completed everything except the survival:endless,where the giant garganter smashes all your plants.I reacahed until the 32 flag until I died.I am thinking on a strategy of putting 4 cob-cannons,that shoots giant corns that kills zombies in that area.Try out the game!
