As noted in yesterdays BlackBerry DevCon general session keynote, the folks from Unity have now started their roll out of games for the BlackBerry PlayBook. Burn the City, Falling Fred and Kona's Crate have all been approved to BlackBerry App World and are available for download. Surprisingly, they're not priced nearly as high as some of the other games we've seen released most recently. All three titles are available for only $.99 cents.
