In Duck N Cover you are a hunter hiding behind a pile of what appears to be sand bags, aiming upward with a rifle at birds that happen to be passing by. You will have a circular sight that you will be able to move around with your mouse, targeting the ducks as they fly by. It is important to keep the round sight on the bird while clicking the left button on your mouse, or else the hit will not count. You will be able to see how many points you have racked up so far on the bottom right hand corner.
You will also be able to see how much ammunition you have left on the bottom left hand side of the screen, and you don't get very much, which is why it's important to get the hard kills that will give you the big points. The ducks that give you the maximum points in this game will be flying around erratically, so never go for the easy kills. If you fail to shoot enough ducks in one round, it will give you a Game Over and the ducks will mock you with their laughing.
At the end of the round, you will see your high score being presented, and the option to enter a user name to record it. Sometimes you will see multiple birds fly on the screen at once, making it even more difficult to shoot all of them before they get away. The main thing to remember is that speed is going to be your best asset, as well as focus.
