Rovio's hit game Angry Birds is landing on Microsoft's Windows Phone 7 platform in early April, along with five other titles.

Microsoft announced the title's inclusion as part of its Spring Showcase event, taking place today in San Francisco.

CNET readers might remember the small kerfuffle that took place prior to the launch of Windows Phone 7, with Microsoft placing an icon of Angry Birds in its online Windows Phone marketing materials. Rovio quickly responded saying it had not committed to doing a version for the platform, and that Microsoft had put the icon on its marketing site without the company's permission. After quickly pulling it down, Microsoft chalked it up as a mistake, saying the graphic was not meant to go live.

Along with Angry Birds, other games that will hit beginning April 6 include: Doodle Jump, Plants vs. Zombies, Hydro Thunder Go, Sonic the Hedgehog 4 Episode 1, and geoDefense. Angry Birds, Hydro Thunder Go, and geoDefense are all being published under the Microsoft Game Studios brand.

Microsoft says all six titles will include integration with Xbox Live for things like leaderboards, achievements, and online presence. Pricing has yet to be announced.
