From the official Rovio website announcement:
We are VERY excited to announce our next game: Angry Birds Space! It’s going to be the biggest game launch since the original Angry Birds!
Angry Birds Space is a completely new game with innovative new gameplay, but with some of the familiar Angry Birds elements that fans already know and love — plus some surprises!
We’re going to announce more information in early March, and on March 22nd we will launch simultaneously in mobile gaming, animation, retail, and publishing. Not only is this a first for us as an integrated entertainment company, but the first time this has ever been done for a mobile game!
Rovio even put together a little teaser video, though it doesn’t show any gameplay yet.
The mind races imagining all the possibilities presented by the concept of Angry Birds Space. Wierd gravity? No gravity? New types of birds? I guess we shall find out soon. So if there are Angry Birds in space, that also means there must be “PIGS… IN… SPAAAAACE!” Sorry, I couldn’t resist a random Muppet Show reference. I can’t wait to give those pigs hell. “In space, no one can hear you squeal.” Okay, I’m done now.
