There's no need for much introduction about these little birds that swept mobile phones last year. A month ago, their developer, Rovio, announced that a PC version would be launched. Today, we bring you the green no-install version of Angry Birds. The gameplay is simple: launch the bird on the slingshot to smash into the green fat pigs. Knocking all the pigs down will allow you to pass the level. The angle and force of the bird's launch is controlled by your finger. You need to carefully consider the combination of force and angle in order to more accurately hit the pigs. The trajectory of the launched bird will be left behind, which can be used as a reference for adjusting the angle and force. Additionally, the more points you earn in each level, the higher your rating will be. Test your calculation skills~ Angry Birds, in order to protect their eggs, have started a battle with the green pigs. Pick up your slingshot and help the birds accomplish their mission on your PC. Note: If the game does not run, please first execute C2008sp1.exe and vcredist_x86.exe in the game directory.
