During the keynote address at Google I/O, Rovio founder Peter Vesterbacka joined the stage to announce an exclusive, desktop browser version of "Angry Birds" for Google Chrome, available now at the Chrome Web Store.
The WebGL-supported game can be played on any WebGL browser, like Chrome and Firefox 4, but when played in Chrome it opens Chrome-specific elements such as Chrome blocks and Chrome bombs, Vesterbacka said. WebGL brings hardware-accelerated 3D graphics to the browser.
The new version also opens the "Mighty Eagle," which was previously available in iOS versions only.
With most modern PCs, users will get over 60 frames per second using WebGL, Vesterbacka said. And the game can be even played offline. "When you Android device runs out of battery, you can continue playing on your PC," Vesterbacka said.
Vesterbacka told the audience he has wanted to bring Angry Birds to the Web for a long time.
Earlier, Google announced developer support for in-app purchases for the first time; previously, all apps were free and monetized by in-app advertsising. Google will charge developers 5 percent of revenues from all virtual goods, an extremely competitive figure next to the Mac App Store's 30 percent demand.
"We really love the 5 percent," Vesterbacka said of the new revenue cut.
In March, Rovio partnered with Microsoft to launch a limited edition version of Angry Birds that integrated Bing Search in its back story.
