As with the original, the premise of Angry Birds HD is to assist a flock of foul fowls to avenge their stolen eggs against a pack of porky piggies. The pigs have run for cover by building rickety homes out of wood, glass, and stone. Place birds in a slingshot and fling them at these targets to topple the structures and pop the pigs. Popping all the pigs a level grants a score based on how many birds you've used. All too often acquiring a 3-star score proved formidable, as only one bird can be used. The 105 included levels should keep your big screen glowing for hours.
