If you are looking for some war action then you should take a look at Island Defense HD. The game is real fun and will keep you going for quite a while. I thought that the app was pretty amusing with its new gameplay that combines tower defense and parking in one. Yes! On docking your ships and parking your planes on the island you earn points that can be used to build towers and defend your island. The game is packed with war ships that keep on coming. I had to forget about surfing or tanning at the beach as I was in for a bloody war experience on Island Defense.
