Love it or hate it, Angry Birds is one of the most successful series of games of all time. Since 2009 when the first game released on iOS, the series has spanned fifteen titles across multiple platforms and become a billion dollar franchise. Six years since the original game released, Rovio has now released the sequel. While it may seem disingenuous to call it Angry Birds 2 considering how many games have been released since the original, it does make sense if you consider others as more of spin-offs of the original rather than sequels. Also, for the first time Angry Birds 2 brings some major changes to the bird-flinging action to warrant the sequel tag. So let's take a look at it, then. At its core, Angry Birds 2 still has you flinging birds at pigs inside elaborate but fragile structures. Break the structures and kill all the pigs before you run out of birds and you complete the stage. Depending upon how much destruction you cause and how many birds you use (fewer the better) you get a score that decides how many stars you get for that stage, three being the highest. That much is common to the original Angry Birds. Now here's the new stuff. Unlike the original, you can now choose which bird to use. The available birds appear at the bottom as cards and you can tap any of them to select whichever bird you think would be more appropriate for the situation instead of being stuck with a preselected bird. As you play more stages, more birds are unlocked. Along with birds, you also unlock spells that can be used to make finishing the level easier. The duck spell rains ducks everywhere and destroys all the pigs in that level in one move. The freeze spell turns all the structures into ice, making it easy for any bird to destroy them. The chili spell makes one of the pig explode, destroying everything around it. As you progress, you unlock more spells. As you cause destruction, you fill up a meter at the top right. When the meter fills up, you get an additional random card, which could either be one of the birds or a spell. This is why it's important to cause as much destruction as possible and not just concentrate on killing the pigs. In Angry Birds 2, each stage has multiple levels within and finishing one level lets you progress to the next with the remaining birds (similar to Angry Birds Epic). When you finish all the levels within a stage (usually 2-4) you move on to the next one. It's important not to use up all your birds at the first level so you have some left for the remaining levels in that stage. If you use up all your birds before that then the game is over. When game is over, you can either choose to continue by paying in gems, or restart that stage. Restarting uses one of the lives you have, and you only have five lives. If you use up all the lives you have to wait for them to refresh (a la Candy Crush Saga), or spend gems to get more lives. As you can tell, gems are important in the game if you're impatient and although you do get them every once in a while as you keep playing if you want more you have to spend real money, which is where the game's IAP component comes in. The birds are more or less identical to the original. There are seven of them, with most of them returning from the original but the weird green one is replaced with a silver one, who instead of flying back like a boomerang flies up and then straight down. All the birds have secondary attacks, even the otherwise useless red one, where you can tap on the screen just before they hit something to activate their ability, such as sending a shock wave for the small red bird, splitting into three for the blue one, shooting in a straight line for the yellow one, dropping an egg bomb for the white one, etc. This does make the game bit more interesting than simply lobbing the birds at the structures and with some planning and clever use of their abilities you can cause far more destruction. Angry Birds 2 has around 240 stages in the current game, with each stage having multiple levels within, so you could be playing this for days. They are split into multiple sections that unlock as you play, and more will be added later. The thing about the stages this time is that they are randomly generated every time. If you restart a stage, the structures get randomly rearranged, which never happened before in any Angry...
