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 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 and a bird known as Silver.

History
This section is in the need of expansion.

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 able to select which birds are desired in the form of cards from a predetermined set. 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 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.

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 was the first game to give Red a permanent ability.
 * Although Corporal Pig has yet to make his debut in a future update for this game, there is technically a Minion Pig who wears Corporal Pig's 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, Stella, and Hal are the only birds from the original game that do not appear in this game.
 * This was 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, 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.
