Angry Birds Space
Angry Birds Space adds a twist to the original Angry Birds titles by setting the levels in a zero gravity environment, but with gravity wells (planets, moons and rocks) spread through each level. As a result it's not longer a game or parabolas, but rather orbits. Also included are new bird characters, scenery, and objects.
The games mechanics are substantially different to the original game, which means a different way of thinking is required to successfully complete each level. For example, some levels require trick shots, such as bouncing off a wall, or getting an orbital insertion just right.
Angry Birds Star Wars
Angry Birds Star Wars combines game play from the earlier titles, with the characters and locations from the Star Wars films. The game also adds new game play mechanics, including light-sabres, blasters and Jedi powers, to help you defeat the Imperial Pigs.
Part of the charm of the game is seeing how Star Wars imagery has been re-imagined with an Angry Birds twists. For example, Tatooine's Mos Eisely's buildings have been subtly modified so they take on the shape of a pig, the original red birds morphs into Luke Skywalker, and the central cabin of TIE Fighters are now pig shaped.
As with other Angry Birds titles there are secret levels and hidden goodies. The game's description challenges you to unlock all the R2D2 and C3PO bonus levels. The titular birds can also be leveled up to improve their skills.
