You can then move your mouse to select a suitable location, and click to place the weapon on the roadside. Click the corresponding tab on the list to select a model, then click the Buy button at the bottom of the list. A list which shows the specifications of the cannons will be presented, listing the power, frequency, range and price for each of the models. When the game starts, you will first be given $1000 to purchase 3 different types of cannons. Can you defend the fortress from destruction and wipe out the invading troops? The castle will be located at the end of a path, and the enemy tanks will travel along the path with the aim to seize the fortress. The last standing castle of the kingdom is under fierce attacks from the enemy.
