Angry Birds 2

Angry Birds 2 (formerly known as Angry Birds Under Pigstruction) is a puzzle platformer game developed by Rovio, first soft launched in Canada on March 5, 2015 and officially released on July 30, 2015. The direct sequel to Angry Birds utilizes new challenges such as multi-stage levels and boss battles (referred to as boss piggies). The game also introduces new features such as spells, cards, feathers, and a bird known as Silver.

Plot
After the events of Angry Birds, Chef Pig steals the eggs and puts them in an airship, 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.

Gameplay
Main Article: Angry Birds 2/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 seven), thus players must defeat multiple fortresses one at a time in order to advance.

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.) In the event only 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.

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.

The lives are shown on the top right of the new screen and campaign map.



As of new version 2.12.2, a new home screen design bought a new layout features the character cards, the right icons redirects into campaign, the arena and daily challenge/King Pig Panic respectively. The bottom shows daily quest, chest and tower of fortune icons.

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.

Level Types
There are various different types of leve in the main campaign: There are a multitude of ways to pop the pigs in Angry birds 2, such as slingshotting a bird directly into a pig, by using abilities or - most commonly - toppling structures that can fall onto the pigs.

 * Hard Level - (AB_2_Hard_Level.png) - Clear all the pigs in a harder difficulty to complete the level. (First introduced in level 9; uncommon to find)
 * 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)
 * Score Level - Score the required points to complete the level. (First introduced in level 14; very rare to find)

Spells AB2 Spells2.png
Spells are powerful cards that can be brought into normal and hard levels in the campaign, as well as in the arena. They are in addition to your normal cards, and when it is selected you are guaranteed to receive at least one randomly in the level. 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.

Reception
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."

Trivia

 * Unlike the original Angry Birds games (Angry Birds, Angry Birds Space, etc.), the birds have their Toons appearance (except for Silver, who made her debut in this game).
 * The game's former name, Under Pigstruction, is a play on Under Construction, an event used to show that the process of construction is taking place.
 * This is the third Angry Birds game after Angry Birds POP! and the Korean version of Angry Birds to feature the lives system. Failing a level will cost a live and after all five lives are used up (All 3 after the Pigsyland update).
 * Now, the lives system is identical to Candy Crush Saga and its sequels (Soda and Jelly) as there are up to 5 lives.
 * This is the first game to give Red a permanent ability.
 * Even though the Corporal Pig appears this game, he's not a boss; he is a Minion Pig that wears a helmet, from Kombo's episodes of Angry Birds Toons.
 * This is the second time a pun on New York City has been made. The first was New Yolk City, the setting of the Super Angry Birds comic.
 * Bubbles is the only bird from the original game that do not appear in this game.
 * However, as seen in the Extra Birds tab, there is a card that does not have any bird and when tapped says Coming Soon!, which is a possibility that it could turn out to be  Bubbles.
 * There is yet another possibility that it could be Bubbles, because the official Angry Birds 2 facebook page posted a video of a gift box shaking and making candy-munching noises with the caption "Almost time to open presents.. What do you think this one has in it?". Bubbles is known for liking candy.
 * This is the second Angry Birds video game that does not have its own Toons.TV video app, after Angry Birds POP!, as pressing the Toons.TV button redirects to a browser version. Now it redirects to its own Toons.TV app.
 * On the Angry Birds Facebook page, a 3 page comic about the story of Angry Birds 2 was released. This strip revealed why Silver was raised by the pigs. They found her as an egg, and she hatched just before getting cooked.
 * When this game is reinstalled, the black pearls will reset to 90.
 * In the World Map/Game Level, players can tap/click on a random pig. The pigs can blow a raspberry, make a face, burp, or fart. If a pig farts, surrounding pigs will groan at the pig who farted, whilst if a pig burps, surrounding pigs will grow angry towards the pig who burped. This will all happen when players tap/click on a pig.
 * Pig Bay is the only chapter with 60 levels so far.
 * This game has the most levels in the Angry Birds series -- 2500. Angry Birds POP! is the second and Angry Birds Seasons is the third.
 * Some of Stella's voice clips are reused from Angry Birds Go!.
 * Hal's appearance is based more on his original design, rather than his new one. Rovio stated that Hal's new beak was too long to appear in the game
