Angry Birds Demo is a strategy puzzle PC game developed by the Finnish computer game developer Rovio Mobile.
Angry Birds Demo allows you to play the initial levels of the game. The full version, which adds hundreds of additional levels can be purchased, in-game at anytime directly from Rovio. In Angry Birds, players control a flock of multi-colored birds that are attempting to retrieve eggs that have been taken by a group of hungry green pigs. On each level, the pigs are sheltered by structures made of various materials such as wood, ice and stone, and the objective of the game is to eliminate all the pigs on the level. Using a slingshot, players launch the birds with the intent of either hitting the pigs directly or damaging the structures, causing them to collapse and eliminate the pigs. In various stages of the game, additional objects such as explosive crates and rocks are found in the structures, and may be used in conjunction with the birds to destroy hard-to-reach pigs.
