The object of Crack'ed is to protect the nesting sights of a rare bird. Armed with your trusty slingshot, you try to pick off the varmints that might steal the eggs.
You start with five eggs to protect. When all the eggs have been stolen or broken, the game is over. Each nesting sight is displayed on a single screen. Egg stealing varmints will enter the screen and try to grab an egg. If you shoot them after they have grabbed an egg, you will have to catch it before it hits the ground and breaks.
You control your aim in Crack'ed by moving a set of crosshairs across the screen. You also use the crosshairs to catch a falling egg. If you shoot an egg-carrying varmint over a nest, the egg will fall into the nest without breaking.
The game rotates through five different nesting sites: tree, sewer, sea, dungeon and moon. The egg-stealing creatures range from the expected owls, snakes and rats to more exotic creatures like ghosts, skeletons, and aliens.
In between each level you pay a visit to the Rooster Ranch. While you are there, you must throw eggs at a sneaky rooster before he can throw one at you.
