While the basic gameplay remains the same – essentially catapulting a variety of birds at a group of heavily armoured pigs – there are now multiple stages in each level and new spells, including “blizzards”, “magic ducks” and “hot chili peppers”.
There are also new characters, including a bird called Silver, which Rovio claims grew up in Pig City and has acquired “porcine habits and an odd sense of humour,” but whose flying skills make her a “powerful new member of the flock”.
According to Rovio, fans can challenge other gamers worldwide and, for the first time, choose their own birds to fling.
“With Angry Birds 2 we wanted to bring a level of expressive depth and detail seen previously only in a console game or animated series – and create a new game that kids and adults alike won’t be able to put down.”
Although it is possible to play the whole game for free, Rovio has introduced a new life system that encourages users to make in-app purchases.
With the Angry Birds 2, the player is given a maximum of three lives, and when they run out, they either have to spend 60 “gems” to continue, or wait 30 minutes for their lives to regenerate. This is somewhat different from the old Angry Birds game.
Gems can be earned during the course of the game, or purchased using real money.
Since launching in December 2009, the original Angry Birds game has been downloaded more than 2.5 billion times. However, despite releasing 10 other spin-off titles, Rovio has failed to replicate the success of the original title, perhaps Angry Birds 2 might see more downloads.
