The object of the game is to score as many points as possible, while making sure that the Hawk doesn't carry Freddy (the man at the bottom left of the screen) away.

There are two ways of stopping this. The first is to wait until the Hawk picks up Freddy and starts carrying him across the screen. You then shoot him and Freddy will fall to the ground. Your task then is to go to the right side of the screen and pick up the basket, and catch Freddy in it. You must then return the basket to where you got it, and pick up your gun again.

The second way is to shoot all the small flies on the screen. This results in the screen being cleared slowly with 50 points being scored for all the small birds still flying or eggs. Freddy and the Hawk are then put back to the beginning, even if the Hawk was carrying him at the time, without any loss of life.

If you fail to stop the bird, then it will drop Freddy on the right side of the screen out of reach and you will lose a life. If you hit the larvae, they will turn into small birds, which fly down and land unless they collide with something. If they collide with something they will turn into larvae and float up again. If they land they will keep bobbing up and down and, if they hit you, you will lose a life.

Larvae that are hit while small birds are already flying down will flash - and when the other bird lands or collides with something will itself turn into a bird and fly down. To stop the birds landing you must place your man into their flight path and stand still.

While flying across to get your man, the large bird drops small eggs to the ground. If your man is hit then you will lose a life. Also when the bird picks up Freddy, eggs are dropped from directly above your man with the gun.

Clearing the flies, or catching Freddy, causes the game to speed up!
