Insect War is a tower defense game in which you have to fight against vicious insects summoned by the evil dark lord. As a lone tank, you have been chosen to defend the kingdom against the onslaught of monsters. Defend your tower, upgrade your tank, defeat waves of evil, and remember, once you die, you can always use your experience to fight again!

The game is very easy to play and does not require any skills whatsoever. In fact, the game is much easier to play if you are not a seasoned tower defense player. You only need to tap the screen to launch a monster at your tower.
