Mega Fortress

You are the guardian of one of the gates of the mega fortress and the enemy is sending wave after wave of cars, tanks and rocket carrying vehicle to attack the gate. At the beginning you will have one mounted gun and one mounted cannon, of which only one can active at any given time so you have to press space bar whenever you want to switch between them. To shoot the enemy, you first need to set your aim by moving the red aiming scope using your mouse, then click on the left mouse button to fire. The gun is weak but can fire continuously so it is good for smaller targets. The cannon is very powerful but takes time to reload and there fore more suitable for bigger targets. As you the enemy attack, you will see the gate's health bar on the left decreasing and as you destroyed the enemy you will get some points as well as some money. When you have enough money, you can spend it on repairing the fortress, buying more cannons, buying more guns, upgrade the cannon so that it reloads faster or upgrade all weapons attack power. After you destroy a wave, the next wave will become more and more powerful but since the fortress is very strong, you should still be able to defend it with carefully aimed shots Fire at will!
