Rovio teases mystery Angry Birds 'alternate reality' game, Seasons Easter eggs may be clues

Rovio has released a cryptic titbit of info about a new "alternate reality" Angry Birds game (which we assume is supposed to read "augmented reality").

Here's the quote from the Rovio press release in all its hazy glory: "Furthermore, we will soon launch the biggest alternate reality game with Angry Birds ever - be prepared to seek for clues around the world to discover the secrets hidden in Angry Birds Seasons!"

This could have something to do with two mysterious 'Easter egg' levels discovered by our resident Angry Birds master Mark Brown.

We have pics of the levels, but to save you from spoilers we've hidden them in the gallery above. Give this story's image a click, and see the second and third images to check them out.
