Angry Birds Go just got very chilly. Rovio has just added a new "Sub Zero" episode to the kart racer, you see.
This new episode contains 18 snow and ice tracks to race across on snowmobiles. Instead of a boss, there's a difficult Slalom race to take on in Sub Zero.
Furthermore, you can buy the new Tar Barreller L1 kart for 2,000 coins. You can unlock the other new karts with gems, Telepod toys, or via a £1.49 / $1.99 IAP.
As you'd hope, you get a chance to earn more coins in the new ice-cold Daily Event, by the way. Just download the update to get all of this new content.
