Rovio's monstrously popular game about foul-tempered fowl migrates to 3DS for the first time with Angry Birds Trilogy. As always, players load a variety of uniquely skilled birds into a slingshot and fire them at green, egg-stealing pigs in an attempt to knock the thieving swine off their pedestals, or crush them beneath falling debris. Gamers can use their stylus to guide the birds through hundreds of levels taken from Angry Birds, the movie tie-in "Angry Birds Rio," and the holiday-themed "Angry Birds Seasons," with all levels supporting stereoscopic 3D and "StreetPass."
