Bad Piggies Build

Bad Piggies Build is a cancelled webgame meant to release in 2012 by Rovio Entertainment, however, this game was never mentioned or announced by the company and was left in mystery until a SWF download was found on the Appspot link. This game was planned to be a successor to the also cancelled Angry Birds Social.

Gameplay
The game consisted of creating your own Angry Birds levels as well as playing other people’s levels and sharing them online.

There was also a story mode of sorts, with you creating different structures to defend the pigs. This was also how you unlocked new blocks.

Trivia

 * Unlike other cancelled games and just like’s precessor, this game was never announced nor confirmed by Rovio, instead it was found in early 2021 via an Appspot link by the Angry Birds community alongside its predecessor Angry Birds Social.
 * This was the second glimpse of an Angry Birds level creator before Angry Birds: Isle of Pigs was created with the first being it’s predecessor.
