Critical Damage

In Critical Damage, you're controlling a spaceship defending your base from waves of enemies. Some enemies drop boxes when they are destroyed - you can collect them to find extra ammo, special features and new effective weapons that are stronger than the regular ones.

There are twelve kinds of weapons you can use and they all have a different level of power. I liked missiles because they were very powerful and could destroy enemies with ease. However, you need to use other weapons too, because you have limited ammo. You can also plant bombs at strategic points to destroy spaceships on their way to your base.

You should act as fast as you can and be careful to prevent the enemies from shooting at the main source of power because if they destroy it, you will lose the game. Critical Damage has good graphics. Before you start playing, you can read the story and find out why you are being attacked. You play this game with your mouse and keyboard arrows. One more advantage is that the game is absolutely free.
