Rovio has just updated Angry Birds Seasons with a special festive pack of levels to keep you flinging birds well into the gloomy December evenings.
You can now go on an Arctic Eggspedition, tossing your avian arsenal through 25 new levels of poorly constructed pig dwellings. There are four extra levels to unlock here, too.
Given this is a wintertime update, everything is cold and frozen, so you can now chuck your birds under the icy sea to spring back up from underneath your piggy foes.
The Arctic Eggspedition update is live on the App Store and the Google Play Store right now if you fancy giving it a crack.
