Angry Birds 2 (known as Angry Birds Under Pigstruction in Canada) is a puzzle platformer game developed by Rovio Mobile, first soft launched in Canada on March 5 and officially released on July 30, 2015. The game utilizes new challenges such as multi-stage levels and boss battles (referred to as boss piggies). The game also introduces a new aids such as spells and a new bird known as Silver.
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 original name, Under Pigstruction was a play on Under Construction, an event used to show that the process of construction is taking place.
This is the second Angry Birds game after Angry Birds POP! 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), the player has to either wait for 30 minutes in order to refill lives, watch a video to get a live for free, or refill all 3 lives by paying for gems.
This was the first game to give Red permanent abilities.
In the other games, Red's battle cry barely does anything.
His power was limited in Red's Mighty Feathers in the first game and as a power-up.
Stella, Bubbles and Hal do not appear in the game. Neither does Corporal Pig. However, Silver's ability is exactly like that of Hal's, and the Puffed-up Pig spell acts exactly like Bubbles' spell, therefore defeating the purpose of those birds' abilities. So far, neither Stella nor a spell referencing her has been added yet however.
It unknown why Corporal Pig does not appear in this game. Technically, there is a Minion Pig who wears Corporal Pig's helmet, from Kombo's episodes of Angry Birds Toons.
