Top 10 iPhone Games of the Year 2011

Every popular fad is met with a backlash, just as every "en vogue" game genre will eventually become oversaturated. This is what has happened to the tower defence genre, one of the early popular game types of the App Store's reign. Anomaly Warzone Earth's makers realised this and decided to do something about it - by turning the genre on its head. In other TD games, you play the role of defender, blasting the invading waves of foes before they reach your base. Yawn, right? Here, you're the invader, carefully planning your attacks to break through the enemy towers' firepower. Apple thought the idea was so neat that it awarded the game with a Design Award.
