Island Clash is a strategy based tower defense game. Your island is under attack and you just cannot sit there crying about it. It is time to get into action. You should set up units in tactical positions on the map to take down all the enemies to prevent them breaking through to the island. The cash earned in the process can be used to deploy more units on the map. As the game progresses, newer weapons and features get unlocked and are worth using against the growing powers of the enemies.
