Angry Birds comes in 3 flavors – Angry Birds, Angry Birds Rio and Angry Birds Seasons, although while the first two are available right away, Angry Birds Seasons will be made available at a latter date.
The survival of the Angry Birds is at stake. Dish out revenge on the green pigs who stole the Birds’ eggs. Use the unique powers of the Angry Birds to lay waste to the pigs’ confounding constructions. Angry Birds features challenging, physics-based demolition gameplay with hours and hours of replay value. Each of the 240+ levels requires logic, skill, and brute force to crush the enemy.
Angry Birds Rio:
The Angry Birds have been captured, caged, and taken to Rio! There they meet new friends, and work together to make their escape from a desolate grey warehouse to the lush green jungle. Help the Angry Birds escape and beat their captors by bombarding the evil marmosets and smashing all obstacles in the way!
Angry Birds will run on Windows 7, Windows Vista and Windows XP SP2.
You can download the free demo versions at the Angry Birds PC Shop. To unlock the full versions, you will have to purchase an activation key at $4.95 for each game.
