PopCap has sneakily revealed its latest project, Pig Up!, currently in beta on Facebook.
The game is a brand new IP, and concerns "piggy aviation".
Comments left on the application's wall suggest the game utilises something called "piggy pence" and that it "rocks socks".
Otherwise, we're in the dark - but we'll try to find out more.
PopCap has made a couple of forays into social gaming in the past, with Bejeweled Blitz a notable success story and Zuma Blitz looking set to follow.
