Only a few days ago, Angry Birds brought 30 new levels to the original game. Well, with the festive season coming around, Angry Birds Seasons—one of the best games on Android—has something in store for you too: 25 new levels, with one being released each day from December 1 till Christmas Day. And it’s all packaged as a new campaign, "Arctic Eggspedition".

"This all-new Angry Birds Seasons episode brings 25 festive, frosty and fun-filled levels, plus another 4 bonus levels!" developer Rovio said in a blog post. "In December, play a new level every day before Christmas as part of our special advent calendar countdown – or unlock them all right away with a simple purchase!"

The obvious change is the theme, which is full of snow-covered levels, frosty pigs wrapped up in earmuffs and heavy jackets, and festive artefacts like Christmas trees, gifts and sleds. It looks pretty cool, but it’s not just about design.

Arctic Eggspedition also brings a new "Underwater Attack" ability for the birds. "Plan a surprise attack by flinging our frosty feathered friends under the icy Arctic waters and up toward those pesky pigs," Rovio advertises on the app stores.

Angry Birds Seasons is a free download. If you are having trouble getting through it, here are some quintessential Angry Birds tips and tricks.
