Gamers will need to get used to using gravity as part of their level solutions. There's a new added power-up called Space Eagles, which is awarded for progressing throughout the game level or can be (ahem) purchased in-app.
The game comes with 60 levels on first download, with, as is typical for Rovio, more coming through game updates.
Samsung Galaxy Note owners will get exclusive content. That will come via the device's Ice Cream Sandwich update. The firmware will include the option to unlock 30 exclusive levels of the Angry Birds Space game if the game is unlocked in the first three months after the update is released. The ICS update is expected to arrive in Q2 of this year. In addition, there will be a branded level, and an exclusive weapon: the Lazer bird.
