A Pig Fortress is what the Bad Piggies build to protect themselves against and slow down the Birds from retaking their eggs. The goal of the game is to kill all the pigs inside the fortresses and destroy the fortress. Pig Fortresses can be in any terrain: Mines, Campsites, Clouds, Normal Terrain, Construction sites, Desert, etc. Most of them are buildings, but some are seen to be methods of transport, for example, a tank-shaped structure in one level and wooden cars in a Golden Egg level. They mainly include materials such as ice, stone, and wood. They eventually get stronger in the later levels. In Angry Birds 2, it is set mainly in the air with plains in Cobalt Plateaus levels, Bamboo in Forest Levels and City in Pig City levels.
