Angry Birds Space update brings 30 new levels and 260 Mirror World levels
Brass Hogs

Rovio has updated Angry Birds Space with a new Brass Hogs chapter today.
It brings with it 30 new levels for you to launch the iconic birds into orbit at those rotten piggies. And, yes, there are planets made out of brass.
There will also be three new daily challenges for the Brass Hogs chapter each day. Completing these missions contributes towards unlocking new levels in the chapter.
Oh, and Wingman is now available as a destructive Power Up. Plus, there are two new achievements to earn.
That's not all, mind. This update also introduces Mirror Worlds to Angry Birds Space.

These Mirror World are unlocked by getting three stars on the regular levels in each chapter (except Eggsteroids and Danger Zone). There are 260 to unlock and complete altogether.
But, if you don't want to put the work in getting all of the three stars, you can spend £4.49 / $5.99 in an IAP to unlock them all.
You can purchase Angry Birds Space for 79p / 99c on Google Play [buy] and the App Store [buy]. It's also available as a free, ad-supported download on Google Play [download].
