Oh no! The world we know is in trouble. The Ultralinks want to destroy it, and they are threatening every single person who tries to stop them. This looks like a perfect mission for Max Steel. However, the Ultralinks are too many, and Max cannot defeat them all alone. He needs your help in the Max Steel: Steel Defense game, to restore peace in the world by beating the Ultralinks. You will control Steel with your mouse and when you see the Ultralinks, quickly click on them to shoot. Be careful because some Ultralinks will take you more than one shot to destroy them. These will stay hidden first, and when they appear, they will shoot you repeatedly. On the right upper side of your screen, there will appear the number of the Ultralinks remaining to shoot. Make sure you fulfill your mission on each level and destroy all the Ultralinks. On the left upper side of the screen, you will see your score. The more enemies you manage to shoot, the higher your score will be! On the lower side of the screen, you will be able to see how many lives you have. You start the levels with five lives, but as the Ultralinks shoot you, you can lose some. Be careful and do not let this thing to happen before you destroy the enemy, or you will have to restart the level. Another important thing is that you have to pay attention to Max or Cytro. From time to time, they will come to help you. Do not shoot them or you will lose points. Good luck!
