PopCap have released 10 new levels for Peggle for free on their site. The 10 brand new levels all carry a World of Warcraft theme, and comprise a standalone fully playable version of Peggle. PopCap have done this before with Peggle Extreme, which was an Orange Box-themed pack originally included in the Orange Box and then later released for free on Steam. More recently, two 5-level season-themed packs have been made available for Peggle Nights on the site.
