Angry Birds 2/Unused Content

Old Name
Angry Birds 2 was first called Angry Birds Under Pigstruction; this was a placeholder name Rovio used for the beta version of the game.

Mighty Eagle Giving Hints
In the game's beta version, Mighty Eagle would appear in the corner of the screen to give the player hints, as opposed to Red who took over this function in the final product.He also takes his appearance from the original game.

Unused Graphics
On the beta, the level score had a different design; it appeared as a piece of blank paper, with a differently shaped Destructo-Meter which also featured a picture of classic Red.

The Beta Slingshot was made with a 3D model instead of a sprite.

Level Completed Screen
On the beta Level Completed Screen, only the birds who were used by the player in any given level would appear, rather than all the birds the player has currently unlocked showing up like they do in the final product.
