Angry Birds 2

Angry Birds 2 is a puzzle video game developed and released by Rovio Entertainment for the Angry Birds series. The game was soft launched in Canada on March 5, 2015 as Angry Birds: Under Pigstruction, and officially released worldwide on July 30, 2015.

History
Initially Rovio Entertainment Corporation stated that they won't make a sequel. However, they started to develop a game involving time travel, that game would be Angry Birds 2 at the time called "Angry Birds Big Adventure (ABBA)". The game was originally about time travel and one of the developers Måns Wilde said that the game was very story driven in early development. These time periods in the game would include:


 * A prehistoric level set on the Mesozoic period;
 * A level inside the King's Diner set on the 70s.

The concept art uses the Toons Designs. Bubbles and Stella appear in some of the concept art.

The game was soft launched in Canada on March 5, 2015 as Angry Birds Under Pigstruction. The game was worldwidely launched on July 30, 2015.

Plot
After the events of the first game, the pigs steal the eggs again. After Level 1 is passed, Chef Pig sucks the eggs to his airship and leaves, leaving Red to gather the rest of the flock pursuing him and the rest of the pigs. After Chef Pig is defeated, the Foreman Pig takes over followed by the King Pig on defeat. It goes on to avoid the birds from recovering the eggs.

The beginning cutscene was removed in later updates, it featured the Angry Birds 2 Cinematic Trailer where the pig steals the eggs, replacing them with sandbags and the flock try to defeat him, which he leaves on the airship.

Cards


There are a number of new changes from the prequel, although the core mechanic of launching birds into Pig Fortresses via the slingshot remains constant. Levels are now selected in the form of an overworld similar to Angry Birds Epic rather than a typical selection screen. Birds are unlocked via accessing treasure chests throughout the overworld. Angry Birds 2 introduces multiple sections labeled as "rooms" in each level (indicated at the top center, and can range from two to eight {1 in the first boss battle}), thus players must defeat multiple fortresses one at a time in order to advance.

There are a multitude of ways to pop the pigs in this game, such as flinging a bird on the slingshot directly into a pig, by using abilities or – most commonly – toppling structures that can fall onto the pigs.

During levels, players are not able to select which birds are desired. Birds/cards are auto assigned from a predetermined set drawn from the pool of birds the player has previously 'unlocked'. Three (3) of these 'bird cards' are presented 'face up' thus revealing their identity. While the remaining cards are in reserve and are presented 'face down' and thus rendering their value hidden. At all times the number of reserve cards is displayed. As a card/bird is used to attack, one of the face down/reserve cards is turned 'face up' and is now active and available for attack. The three (3) 'face up'/active cards can be used in any order the player wishes. This differs greatly from previous iterations of Angry Birds, as the order of birds until this installment were locked, meaning the player could not choose which birds to fire at their momentary need. A "Destruct-O-Meter" on the upper-right of the screen accumulates points from playing through levels, and filling up the bar will reset it and award the player with an extra bird card. In the event that the player already has three (3) bird cards 'face up' the awarded extra card will be placed 'face down' in the reserve deck. (Note: as the card travels to the reserve deck the identity is NOT hidden) One bird is used to destroy a fortress, it is referred to as a "Strike!" (such as in bowling) or two birds was used "Birdie!" (spare), earning additional points towards the score.

Bird cards can be upgraded by collecting feathers. The higher your card ranks are, the more scores you earn throughout each level.

Level Types
There are various different types of level in the main map:


 * 1) Normal Level (AB_2_Normal_Level.png) – Clear all the pigs to complete the level. (First introduced in level 1; common to find)
 * 2) Hard Level (AB_2_Hard_Level.png) – Clear all the pigs in a harder difficulty to complete the level. (First introduced in level 24; uncommon to find)
 * 3) Boss Level (AB2_Boss_Icon.png) – Beat the boss pig in the last room to complete the level. (First introduced in level 5; each chapter has at least 3 of this level type; the rest of the chapters after level 240 have 6, while Pig Bay has 9, featuring the bosses Chef Pig, Foreman Pig, and King Pig in cycles) The boss can be beaten by:
 * 4) * using the birds to hit him repeatedly until his health is depleted; or
 * 5) * pushing him out of the screen.
 * 6) Score Level – Score the required points to complete the level. (First introduced in level 18; only 4 exist in the first 90 levels and possibly the whole game)

Lives
Unlike previous games where players could fail levels without consequence or retry levels as many times as needed, Angry Birds 2 features the usage of lives where there are a limited amount of attempts allowed. This means that the player must have at least one life in order to play a level. The game starts out with five lives, one is deducted every time a level is failed or the player forfeits (There was a special offer that allowed the player to have six lives). Lives regenerate slowly over time (one per thirty minutes), but the player may purchase additional lives to use on demand. It is impossible to lose a life if the player does not launch any birds at the beginning of the level.

Star Rank
The star rank is a new feature in which players accumulate stars to level up the rank currently in their possession. It can be earn through campaign levels or /The Nest/. It is displayed on the top left of the screen in campaign map and home screen.

Spells will rank up if all the birds (and slingshot) have reached the specified level (unless all the birds' level are inconsistent, the lowest level will be applied to spells). For example, if all your birds are at rank 18, except Red who is at Rank 17, then the spells will be at Rank 17.

Tower of Fortune


The Tower of Fortune is a place you can win rewards, such as Gems, Black Pearls, Spells, Feathers and Hats. But be careful in most levels there is a pig card (1/4 chance) will ready to steal all your rewards you have gained – in case you encounter him, you either have to spend Gems to get rid of him to continue, or quit the tower with all your rewards lost. You can exit the tower with your rewards at hand any time before you proceed to the next level.

Mighty Eagle's Bootcamp is a daily training. Pass Level 38 in order to unlock it. If you get a really high score, you might be featured on the Top 100 global leaderboard! Each season is 47 days long. In the shop, you can buy many things like chests, exclusive hats, special animated avatars, and much more! At the end of each season your frame resets, but your frame will be converted into Mighty Eagle Coins depending on how high your frame level is, so it's not a total loss! The shop will always be open, so the player has to play the challenge more often to get all the great rewards! If you play the training you will get Mighty Eagle Coins depending on how far you go in the training. You also get Mighty Eagle Points depending on how high your score is. Each day, remember to collect your Mighty Eagle Points to upgrade your frame.

Critics
The game has received mixed reviews. Pocket Gamer gave the game a 7/10, feeling that the gameplay was a step forward in puzzle design and the graphics were gorgeous—however, it did not like the energy system that, after failing to complete a few levels, either makes the player stop playing or use gems to continue playing; overall the website thought the game was Rovio at its best. IGN awarded it a score of 6.7 out of 10, saying "Ever-shifting levels and limited lives take a lot of the fun out of smashing pigs with birds in Angry Birds 2."

Users
The game received generally unfavorable reviews from fans on Metacritic, The main criticism fans had was the live system, the microtransactions, and the lack of difficulty.
