Power-Up Test Site

Power-Up Test Site, or simply Test Site, is an additional episode of Angry Birds Seasons. It was added in October 2015 along with Invasion of the Egg Snatchers. It is composed on five levels.

Description
Power-Up Test Site takes the appearance of a facility located in a desert during daytime. Some canyons can be spotted in the background underneath a clean, light blue sky with some clouds. There are also some cactuses in the front layer of the levels.

Gameplay
As with all the other episodes in the game, the main goal of Power-Up Test Site is to pop all the pigs in the levels by launching a limited set of birds using a slingshot. In addition, the player will also have free access to all the Power-Ups in the game, though they will only be able to use each of them once.

Trivia

 * Some letters with the test "NEST 51" appear in Power-Up Test Site, referencing Area 51.
