Command the troops of rebels at the Battle of Steampunk Tower and fight against the evil Empire. There are 4 kinds of cannons you can buy in the game: thunder, claw, axe and wasp 1. Some of them have low fire speed, some are inefficient against heavy armor. After you build the weapons you can upgrade them with the money you earn or even sell them if you want to change the strategy. Move the guns from one side to another on the tower defense to be more efficient and win the battles.
