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 in the Mezozoic period and a level inside the King's Diner set in the 70s.

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

Plot
At the Cobalt Plateaus, while the Angry Birds are sleeping, a Minion Pig approaches and steals their eggs, replacing them with sand bags. However, as he is about to leave, it is too late, as the Angry Birds have already spotted him, so the Minion Pig tries to escape with the eggs. despite the odds, he somehow manages to survive, and hops onto an airship with other Minion Pigs and King Pig on it. King Pig, having finally managed to get the eggs, laughs at the birds and leaves with the eggs. Enraged, the Angry Birds start to chase the pigs, rescuing other partners in the adventure, who join them.

Gameplay
Trying to emulate the gameplay style of past Angry Birds games, Angry Birds 2 is a physics-based puzzle video game. As with similar games, the main objective is to pop all the pigs in the levels, who are sheltered inside of structures made of glass, wood and stone, alongside other objects. To pop said pigs, the player has to launch a limited group of characters using a slingshot. If they run out of characters without popping all pigs, they will pay gems or free bird tokens to continue or get a Level Failed screen and lose a life.

The main feature of Angry Birds 2 is the player being able to choose which character are they going to use; these characters are represented with cards. Every time, the player will only be able to choose up to three characters, while the other ones will appear as the characters are being launched. Because of this, certain characters can work better on certain structures, while they be weaker on other ones. Levels are divided into a series of "zones", one following the other. When all pigs in a zone are popped, the player will pass to the next zone, and so on until they complete the level. After beating a level, the player will get one, two, or three stars depending on their performance.

To launch a character, the player has to put their finger on the slingshot and drag it to aim. While aiming, they will be given a trail of white dots that will predict the area the character is going to travel through. Releasing the finger will result in the character being launched. In this state, the player can tap anywhere onto the screen to make them perform their special ability. However, they will only be able to use it once, and will not use it if they collide with any surface. Once the character is launched, the player will be unable to use them again; to compensate this, the game uses the Destruct-O-Meter, a gauge that will be filled as the player destroys buildings and pop the pigs. When full, it will empty itself and give the player an extra card.

Levels
The game story is followed on a World Map where the player can select a level to play. Levels are randomly generated (but always with the same maximum score achievable) and are divided into several categories:
 * Normal Level: The player has to clear a series of zones by popping pigs. First appeared in level 1.
 * Hard Level: Similar to the Normal Levels, but with a higher difficulty. First appeared in level 24.
 * Score Level: The player has to get a certain amount of points. These levels have infinite zones, though they end as soon as the player gets the points asked for. These levels are the rarest in the game. First appeared in Level 18 and last in Level 63.
 * Boss Level: Similar to the Normal Levels. However, the last zone, a boss pig will appear and the player must defeat to win. The boss has a health gauge that will tell the boss' health. Emptying the gauge will defeat the boss and the pigs. First appeared in Level 5.

Bird Ranks
Ranks are the level of the birds in Angry Birds 2. The rank affects the multiplier of the score, meaning a higher level will achieve a higher score, filling the Destruct-O-Meter faster.

Hatchling
The hatchling is an egg near the slingshot that boosts the score multiplier. It needs to be feed daily to level up, otherwise it will leave and the score multiplier will reset.

Hats
The Hats are optional cosmetics that give an additional multiplier to the player's main birds. Said hats are divided in different sets, and can be purchased with Black Pearls. Collecting all the hats from the same set will upgrade the slingshot, and will give the player more Bird Power. The Hat Shop also has a Black Pearl treasure chest, which can be opened every twenty four hours.

Daily Quest
The Daily Quest is a set of six different challenges the player gets every day.

Daily Challenge
Daily Challenges are an optional mode that tasks the player with completing three levels without failing. The Daily Challenges are as follows:
 * Red's Rumble!: Played on Mondays. Has Red as the title character.
 * Blues' Brawl!: Played on Tuesdays. Has Jake, Jay and Jim as the title characters.
 * Chuck's Challenge!: Played on Wednesdays. Has Chuck as the title character.
 * Matilda Mayhem!: Played on Thursdays. Has Matilda as the title character.
 * Silver Slam!: Played on Fridays. Has Silver as the title character.
 * Bomb's Blast!: Played on Saturdays. Has Bomb as the title character.
 * Terence Trial!: Played on Sundays. Has Terence as the title character.

After completing one of these Daily Challenges, the player will be able to play King Pig Panic!, three difficult boss levels that will give the player great awards when completed.

Mighty Eagle's Bootcamp
The Mighty Eagle's Bootcamp is unlocked after passing level 38 in the normal mode. It rewards Mighty Eagle Points and Coins depending on how far the player makes it in the daily training. Based on their performance, the player will receive a portrait frame. When a new season starts, everyone's scores and frames are reset.

Tower of Fortune
The Tower of Fortune is a place where the player can win rewards, such as Gems, Black Pearls, Spells, Feathers and Hats. In every floor, they will be given four cards to choose, one of which having a pig card that will steal all their rewards if it is picked up. In the floors that are multiple of five however, there will only have hats to choose. The player can leave whenever they want and claim their rewards.

The Arena
The Arena is a player versus player-styled mode where the players are matched based on skill rating. Every day, five birds are chosen for the Flock of the Day and are the only ones that can be used. Weekly, the player is matched with thirty other players of similar skill rating and will receive rewards based on the leaderboard result (who can gain the most rating in a week). The Arena gives rewards every fourty five days based on the player's league achieved and performance in the season.

Events
Events are active for a limited time and offer great opportunities for some rewards. If there is an event active, it will be indicated by a timer at the bottom of the title screen, and the different icons show the player which events are active at any given time. Some of the events that can appear are as follows:
 * Rowdy Rumble!: The player will have to get a higher score than their opponent. If they win battles, they will make it to the top. The higher they are, the more rewards they will get.
 * Hatchling Fever!: The player's hatchling multiplier boost is doubled or tripled and more apples appear. This is only for the players who have a hatchling.
 * Mini Events: Player must collect as many as possible to make it on the top. The events can be easy ways to collect extra rewards. For example, if the theme of the events is "Flying Matilda, fly!", the player will need launch Matilda as many times as possible before time runs out.
 * Black Pearl Party!: All Black Pearl rewards are doubled during the event.
 * Jetpack Run: The player's hatchling will put on a jetpack. They will have to guide them on an apple hunt and avoid to touch obstacles to improve their score.
 * Feather Frenzy!: All Feather rewards are doubled during the event.
 * Rainbow Fever!: All Feather rewards are turned to Rainbow Feathers during the event.
 * Event shop: The Event Shop is where the players can buy special items using the Event Coins. Event Coins can be get in different parts of the game. They are linked to each event and will expire when the event ends, where they will turn into Rainbow Feathers.
 * Bird's Fever!: Certain character's Bird Power is tripled during the event. For example, if the theme of the events is "Hal's Fever!", Hal's power is tripled. This is only for players who have unlocked said bird. This event can be only used from extra birds.
 * The Birds Adventures and Hat Adventures: These events are themed after a Hat Set or extra birds. The player will only be able to play with the birds that own these hats or extra birds. For example, if the theme of the events is "The Hal Adventure!", the player will help Hal complete all levels to get all rewards. Rewards are used such as Black Pearls, Rare Chest, Feathers and Legendary Chest.
 * Playing For the Planet!: Player must pop a bunch of pigs to reach the global goal.

Feats
Similar to achievements in Game Center or Google Play, these are missions that are intended to be completed over a longer period of time than the daily quests. Rewards for the feats include Feathers, Gems, Black Pearls, and Chests.

Clans
Clans are groups of players that join together in order to compete with other Clans or to complete Clan Events.

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."
