Now, I'm not one to normally play games or, in turn, get addicted to playing games, but this one is amazing. Like all of the best things in the category of "things I would call amazing", the plot behind Plants vs Zombies is easily explained. In fact, it's essentially in the title.
You are a homeowner in Zombie-Infested suburbia. Besides 'Crazy Dave' (your neighbour and only human compatriot) you are friendless in a world of Brain-Hungry-Zombies. Your only chance to survive? By planting clever shrubs that inflict damage on the advancing undead is quickly and strategically as possible. Plants cost sunlight which is generated by sunflowers. The more sunflowers you plant, the more sun you have, the more you can build up your garden (ie: fortress).
Your arsenal ranges from fast firing pea-shooters to slow timing potato-mines. You've got wallnuts that'll act as shields and cherry bombs that'll blow up anyone nearby. There's everything, melon catapults, corn-cob-cannons, and they all come accompanied with hilarious back stories.
Check it out from the
official website, there's a free trial download that gives you one hour of playing time, but be warned, it is very very
very addictive.
At least it was for me, I mean, I can't even pick flowers for my girlfriend now without considering the consequences...
