As you might expect, there have been some changes made to the game since the original version. That’s not unusual for any mobile game that has a 2 in it’s name. For example, there were huge visual differences between Zynga’s Farmville and Farmville 2.
Ubergizmo reports that much of the gameplay in Angry Birds 2 is similar to the original Angry Birds. The new version includes animations, new effects, and dynamic lighting that Rovio was unable to put into the original version (which was released in December of 2009).
The game now includes cards, which players can earn by destroying things. The more things a player destroys, the more cards he or she receives. Every fifth level is a boss level. Players can use feathers to level up the birds, and can choose which order they want to play the birds in. There appears to be more strategy involved in Angry Birds 2 than there was in the original Angry Birds.
Angry Birds 2 includes in-app purchases Players start the game with 3 lives. When players run out of cards, they have to stop playing. The player can either wait 30 minutes for the lives to regenerate, or can spend real world money on gems. It takes 60 gems to recharge one life.
Obviously, Angry Birds 2 is not the only mobile game that includes in-app purchases. Many of them do. It is up to the player to determine if it is worth it to them to spend real world money to continue playing Angry Birds 2 right now, or if it is a better idea to do something else for 30 minutes while the lives recharge.
